Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
O A. The slope equals
(Simplify your answer.)
B. The slope is undefined.

Answer 1

The slope equals -⁴/3

Explanation:

Slope of the line passing through the origin (0, 0) and (-9, 12):

Slope =
`(y_2 - y_1)/(x_2 - x_1) = (12 - 0)/(-9 - 0) = (12)/(-9) = -(4)/(3)`

Slope (m) = -⁴/3
