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 toy rocket lifts off at an initial velocity of 102 feet per second from a height of 10 feet. The height of the rocket can be modeled by the equation h = – 16t2 + 102t + 10, where ‘t' is the time in seconds. When will the rocket hit to the ground?
Answer:
6.47secs
Step-by-step explanation:
Given the height of the rocket modelled by the equation;
h = – 16t^2 + 102t + 10, where ‘t' is the time in seconds
The rocket will hit the ground at h = 0
Substitute into the equation
– 16t^2 + 102t + 10 = 0
Multiply through by -1
16t^2-102t-10 = 0
t = 102±√(102)²-4(16)(-10)/2(16)
t = 102±√10404+640/32
t = 102±√11044/32
t = 102 ±105.09/32
t = 102+105.09/32
t = 207.09/32
t = 6.47secs
Hence it will take 6.47secs for the rocket to hit the ground

Edwin has $50.00 in his bank. He starts spending $2.50 each week on snacks at lunch graph it
Answer: 50.00 - 2.50 each week
Answer:
Step-by-step explanation:
First label the x axis as "Time (Weeks)" and y axis as "money in the bank account". The x axis should go by 1. As in the squares being, 1,2,3, etc. The y axis should go by 5's and end at 50. Plant a dot at coordinates (0,50) and continue by subtracting $2.5 per week. So the next coordinates should be (1, 47.5). In the end, there should be $25 left in the account (after using all of the boxes).
