Question

Use the slope formula to find the slope of the line that passes through the two given points. State whether the line is​ increasing, decreasing,​ horizontal, or vertical.

​(3​,7​) and ​(9​,6​)

Answer 1

The slope is -1/6.

Using the slope formula m = (y₂-y₁)/(x₂-x₁),

m = (6-7)/(9-3) = -1/6

Because the slope is negative, the line is decreasing.
