What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
Slope = (d - b) / (c - a)
Where (a, b) and (c, d) are the two points.
Now,
The slope between (-10, -12) and (-8, -8) is 2.
The slope between (-8, -8) and (-6, -4) is 2.
The slope between (-6, -4) and (-4, 0) is 2.
Therefore,
The slope of the line passing through these points is 2.
The slope between (-4, 2) and (0, 1) is -1/4.
The slope between (0, 1) and (4, 0) is -1/4.
The slope between (4, 0) and (8, -1) is -1/4.
Therefore,
The slope of the line passing through these points is -1/4.
The slope between (-7, -7) and (0, -8) is -1/7.
The slope between (0, -8) and (7, -9) is -1/7.
The slope between (7, -9) and (14, -10) is -1/7.
Therefore,
The slope of the line passing through these points is -1/7.
The slope between (-2, 2) and (0, 3) is 1/2.
The slope between (0, 3) and (2, 4) is 1/2.
The slope between (2, 4) and (4, 5) is 1/2.
Therefore,
The slope of the line passing through these points is 1/2.
The slope between (2, -11) and (4, -25) is -7.
The slope between (4, -25) and (6, -39) is -7.
The slope between (6, -39) and (8, -53) is -7.
Therefore,
The slope of the line passing through these points is -7.
The slope between (-11, -38) and (-5, -14) is 6.
The slope between (-5, -14) and (1, 10) is 8.
The slope between (1, 10) and (7, 34) is 6.
Therefore,
The slope of the line passing through these points is 6.
Now,
The equation in slope intercept form is y = mx + c
where m is the slope of the line and c is the y-intercept.
So,
The slope of y = -4x + 6 is -4 and the y-intercept is 6.
The equation y = -1 represents a horizontal line, so the slope is 0 and the y-intercept is -1.
To find the slope-intercept form, we can rewrite 4r + y = -1 as y = -4r - 1.
Therefore,
The slope is -4 and the y-intercept is -1.
The slope of y = 6x - 4 is 6 and the y-intercept is -4.
To find the slope-intercept form, we can rewrite -x - 4y + 8 = 0 as -4y = x - 8, then divide both sides by -4 to get y = (-1/4)x + 2.
Therefore,
The slope is -1/4 and the y-intercept is 2.
To find the slope-intercept form, we can rewrite 2r - 12y + 10 = 0 as 12y = 2r + 10, then divide both sides by 12 to get y = (1/6)r + 5/6.
Therefore,
The slope is 1/6 and the y-intercept is 5/6.
Thus,
The slope and the y-intercept are given above.

a baseball team has won 25 games and lost 12 games. if the baseball teams rate continue through a 148 game season, then how many games will they have won?
Answer:
100 games won
Step-by-step explanation:
1. 25 games won and 12 games lost is a total of 37 games
2. If you're comparing the 25 games out of 37 games won to a total of 148 games played and trying to find the number of games won you would multiply 25 times 148 divided by 37

A 36-foot long rope is tied from the top of a pole to a stake in the ground. If the stake is 17 feet from the base of the pole, find the height of the pole. Round to the nearest tenth if necessary.
Answer:
Perpendicular = 31.73 ft (Approx)
Step-by-step explanation:
Given:
Length of rope (Hypotenuse) = 36 ft
Base = 17 ft
Find:
Height of pole (Perpendicular)
Computation:
Perpendicular = √Hypotenuse² - Base²
Perpendicular = √36² - 17²
Perpendicular = √1,296 - 289
Perpendicular = 31.73 ft (Approx)
At the beginning of a population study, city had 210,000 people. Each year since, the population has grown by 5.5%. Let t be the number of years since the start of the study. Let y  be the cities population. Write an exponential function showing the relationship between y and t. 
Y=
Answer:
y = 210,000(1.055)^t
Step-by-step explanation:
Initial population: p = 210,000
Annual growth rate: 5.5% = 0.055
Number of years: t
Population in year t: y
y = p(1 + r)^t
y = 210,000(1 + 0.055)^t
y = 210,000(1.055)^t

Rewrite the function f(x)=4(x-2)²-8 in the form f(x)=ax²+bx+c.
Answer:
4[tex]x^{2}[/tex]-16x+8
Step-by-step explanation:
4(x - 2)(x - 2) - 8 = 4([tex]x^{2}[/tex] - 4x + 4) - 8 = 4[tex]x^{2}[/tex] - 16x + 16 - 8 = 4[tex]x^{2}[/tex] - 16x + 8.

f(x)=4(x-2)² Simplify.
f(x) = 4x^2 - 16x + 16

Jack and beth are selling wrapping paper for a school fundraiser. Customers can buy rolls of plain wrapping paper and rolls of shiny wrapping paper. Jack sold 5 rolls of plain and 8 rolls of shiny for a total of $190. Beth sold of 5 rolls plain and 3 shiny for a total of $90. Find the cost of each roll of wrapping paper
Answer:
Cost of a roll of plain wrapping paper = $6
Cost of a roll of shiny wrapping paper = $20
Step-by-step explanation:
Let [tex]x[/tex] denotes cost of a roll of plain wrapping paper and [tex]y[/tex] denotes cost of roll of shiny wrapping paper.
Jack sold 5 rolls of plain and 8 rolls of shiny for a total of $190.
[tex]5x+8y=190\,\,\,(i)[/tex]
Beth sold of 5 rolls plain and 3 shiny for a total of $90.
[tex]5x+3y=90\,\,\,(ii)[/tex]
Subtract (ii) from (i).
[tex]8y-3y=190-90\\5y=100\\y=20[/tex]
Put [tex]y=20[/tex] in (ii)
[tex]5x+3(20)=90\\5x+60=90\\5x=90-60\\5x=30\\x=6[/tex]
Therefore,
Cost of a roll of plain wrapping paper = $6
Cost of a roll of shiny wrapping paper = $20
