Answer:

y = 4/5x -3

Step-by-step explanation:

in order to do this :

firstly , find the midpoint of the points.

use the formula :

[tex]\frac{x1 + x2}{2} , \frac{y1 + y2}{2}[/tex]

= [tex]\frac{-5 + 5}{2} , \frac{-7 + 1}{2}[/tex]

midpoint =(0 , -3)

secondly , get the gradient

use the formula :

[tex]\frac{y2-y1}{x2-x1}[/tex]

= [tex]\frac{1-(-7)}{5-(-5)}[/tex]

=[tex]\frac{8}{10}[/tex]

simplified to 4/5

gradient = 4/5

Thirdly , create the equation

formula for the equation of a line

(Y-y1) = m( X-x1)

now use the values of the midpoint and the gradient(m)

y +7 = 4/5 (x + 5)

y = 4/5x + 4-7

y = 4/5x -3

Answer:

y = 0.8x - 3

Step-by-step explanation:

Slope = (-7-1)/(-5-5) = -8/-10 = 0.8

When x = 5, y = 1

1 = 0.8(5) + c

1 = 4 + c

c = -3

y = 0.8x - 3
