# If A has coordinates 2 ,   1 and B has coordinates x ,   3 , find x so that the slope of A B ⃡ is - 3 .

To determine

To find:

The value of x so that the line AB with vertices A2, 1 and Bx, 3 has slope m=-3.

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 A2, 1 and Bx, 3.

Using the slope formula and choosing x1=2, x2=x, y1=1, y</
