What is an equation of the line that passes through the points (−5,−7) and (5,1)?

y = 4/5x -3

Step-by-step explanation:

in order to do this :

use the formula :

=

midpoint =(0 , -3)

use the formula :

=

=

simplified to 4/5

gradient = 4/5

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 = 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

14

step-by-step explanation:

14 x 3 = 42
