9. write an equation of the line that passes through the points (3,7) and (5,11)

 is the required equation of line.

Step-by-step explanation:

To find the equation of line    through (3, 7) and (5, 11) we first need to find the slope of line and then y-intercept.

Use one point and slope to find the y-intercept.

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
