Question

What is the slope of the line that passes through the points (-9, 8) and (–21, 10)?
Write your answer in simplest form.

Answer 1

Answer:

-1/6

Step-by-step explanation:

We can use the slope formula

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

   = ( 10-8)/(-21 - -9)

  = ( 10-8)/(-21 +9)

   = 2 /-12

  = -1/6
