Answer:

Explanation:

Equation of a line

y = mx + c

Given two points

( 8 , -3) ( 8 , 4)

Step 1: find the slope

m = y2 - y1 / x2 -x1

( 8 , -3) ( 8 , 4)

x1 = 8

y1 = -3

x2 = 8

y2 = 4

Insert the values

m = 4 - (-3) / 8 - 8

= 4 + 3 / 0

= 7/ 0

Step 2: substitute any of the two points given into the equation

y = mx + c

( 8 , 4)

x = 8

y = 4

4 = 7/0 * 8 + c

c =

m can't be 7/0, that is math error which means that the points are not correct
