Math Problem Statement

Find the slope of the line that travels through the points (-3,-8) and (2,2). Simplify your final answer. If the slope is undefined then type undefined.

Solution

To find the slope mm of the line that passes through the points (3,8)(-3, -8) and (2,2)(2, 2), use the slope formula:

m=y2y1x2x1m = \frac{y_2 - y_1}{x_2 - x_1}

where:

  • (x1,y1)=(3,8)(x_1, y_1) = (-3, -8)
  • (x2,y2)=(2,2)(x_2, y_2) = (2, 2)

Substitute these values into the formula:

m=2(8)2(3)m = \frac{2 - (-8)}{2 - (-3)}

Simplify:

m=2+82+3=105=2m = \frac{2 + 8}{2 + 3} = \frac{10}{5} = 2

So, the slope of the line is:

2\boxed{2}
