Question

A line with a slope of

–
6 passes through the points (
–
6,
–
5) and (
–
7,c). What is the value of c?

Answer 1

c=11

Explanation:

We have two points ( 6,5) and (7,c) and a slope of 6

The slope formula is

m = ( y2-y1)/(x2-x1)

6 = (c-5)/(7-6)

6 = (c-5)/1

6 = c-5

Add 5 to each side

6+5 = c-5+5

11 =c
