Question

Determine the slope of the line that goes through the points (-9,14) and (9,-2)

Answer 1

Answer:

-8/9

Step-by-step explanation:

To find the slope of a line using two points, the equation is y2 - y1/x2 - x1.

In this example,

y2 = -2

y1 = 14

x2 = 9

x1 = -9

Plug the points into the equation.

y2 - y1/x2 - x1

-2 - 14/9-(-9)

Next, simplify.

-16/18

-8/9

m = -8/9
