Answer:

Option C

Step-by-step explanation:

We want to select the expression that can be used to find the slope of the line going through the points (–7, 3) and (1, –9)

Recall that the slope is given by:

[tex] \frac{y_2-y_1}{x_2-x_1} [/tex]

We substitute the points into the formula to get:

[tex] \frac{ - 9 - 3}{1 - - 7} [/tex]

Therefore the third choice is correct.
