The points (4,1) and (x,-6) lie on the same line. if the slope of the line is 1, what is the value of x?

x=-3

Step-by-step explanation:

The slope is given by  

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

We have points (4,1) and (x,-6) and the slope is 1

Substituting these in

1 = (-6-1)/ (x-4)

Simplifying

1 = (-7) / (x-4)

Multiply by (x-4) on both sides

(x-4) = -7

Add 4 on both sides

x-4+4 = -7+4

x=-3
