Find x so that A B - has slope m , where:a) A is 2 ,   - 3 , B is x ,   5 , and m = 1 b) A is x ,   - 1 , B is 3 ,   5 , and m = - 0.5

To determine

(a)

To find:

The value of x so that line AB with vertices 2, -3 and x, 5 has slope m=1.

Explanation

The slope of the line that contains the points x1,y1 and x2,y2 is given by

m=y2-y1x2-x1 for x2x1

The given points are 2, -3 and x, 5

To determine

(b)

To find:

The value of x so that line AB with vertices Ax, -1 and B3, 5 has slope m=-0.5.
