Write an equation of the line that passes through (4,−1) and is parallel to the line y=3x+7.
Answers
The equation of the line that passes through (4,−1) and is parallel to the line y=3x+7 will be y = 3x - 13.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given that line that passes through (4,−1) and is parallel to the line y = 3x+7. If the line is parallel then the slope will be equal to the parallel line.
m = 3
The equation of the line will be written as,
y = 3x + c
The y-intercept will be calculated as,
y = 3x + c
-1 = ( 3 x 4) + c
c = -13
The equation will be,
y = 3x - 13
Therefore, the equation of the line that passes through (4,−1) and is parallel to the line y=3x+7 will be y = 3x - 13.

Grace measured a line to be 15.6 inches long. If the actual length of the line is 15.3
inches, then what was the percent error of the measurement, to the nearest tenth of a
percent?
Answers
The percentage error of the measurement, to the nearest tenth of a percent 2.6%.
Given, Grace measured a line to be 15.6 inches long.
The actual length of the line is 15.3 inches.
Percentage error of the measurement = ?
Error in the measurement = 15.6 - 15.3
= 0.3 inches
Percentage error = 0.4 ÷ 15.3
= 0.02614 × 100
= 2.6%
The percentage error = 2.6%
Hence the percentage error is 2.6% .

Find the equation of the line that passes through the given points. Write the equation in slope-intercept form.
(-2.7) and (-1,5)
Answers
Answer:
The equation in the slope-intercept form will be:
y = -2x + 3Step-by-step explanation:
Given the points
(-2, 7)(-1, 5)Finding the slope between the points
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-2,\:7\right),\:\left(x_2,\:y_2\right)=\left(-1,\:5\right)[/tex]
[tex]m=\frac{5-7}{-1-\left(-2\right)}[/tex]
[tex]m=-2[/tex]
We know that the slope-intercept of line equation is
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept
substituting m = -2 and the point (-2, 7) to find the y-intercept 'b'
y = mx+b
7 = -2(-2) + b
7 = 4 + b
b = 7-4
b = 3
so the y-intercept = b = 3
substituting m = -2 and b = 3 in the slope-intercept form of line equation
y = mx+b
y = -2x + 3
Thus, the the equation in the slope-intercept form will be:
y = -2x + 3The graph of f passes through (-2,7) and is perpendicular to the line whose equation is x= -16.
The equation of the function is
Answers
Answer:
y = 7
Step-by-step explanation:
x = -16 is a vertical line.
All lines perpendicular to a vertical line are horizontal lines. All horizontal lines have a slope of 0
so m = 0, y = 7, x = -2
y = mx + b
7 = 0(-2) + b
b = 7
so,
y = 0x + 7
y = 7

a group of college students eager to get to florida on a spring break drove the 750- mi trip with only minimum stops. they computed their average speed for the trip to be 55.0 mi/h. how many hours did the trip take?
Answers
The trip took 13 hrs . and 6 min .
Given : Distance of trip from starting point to end point = 750 mi
Avg . speed for trip = 55 mi / h
To find : how many hours did the trip take
Using formula for speed :
speed = distance / time
Substituting values in above formula ,
and let time = t .
55 = 750 / t
t = 750 / 55
t = 13 . 63
≈ 13 hrs . 6 min .
Hence , the trip took 13 hours approx .
