If a line is parallel to another it has the same slope. Since the equation y = 1/3x +8 is parallel to the line we are trying to find, our second line will have the slope of 1/3x as well
This is the equation of a line:
y = mx + b
m = slope = 1/3x
b = y intercept = unknown
We have to find b to make this equation complete. How do we do this?
First plug what you know into the equation: y = 1/3x + b
Second we must solve for b. To do this plug a point that passes through the line (in this case they said (6, -2) passes through the line) into the x and y of the equation:
-2 = 1/3(6) + b
Now solve for b!
-2 = 6/3 + b
-2 = 2 + b
- 2 - 2 = b
-4 = b
The equation parallel to y=1/3x + 8 and passes through point (6, -2) is y = 1/3x - 4
The image below is the two line one a coordinate plane. As you can see, they are parallel to each other

Answer: c. 91
Step-by-step explanation:
Given : A linear regression equation was computed to predict the final exam score from score on the midterm exam.
The equation of the least squares regression line was
, where y= the final exam score
x= the midterm exam score.
if Joe score a 90 on the midterm exam, the put x= 90 in the above eqaution , we get
Hence, the predicted value of his score on the final exam would be 91.
Therefore , the correct answer is c. 91 .
