Question

What is the slope of the line through (-1, -7) and (3,9)? Choose 1 answerA. -1/4B. -4C. 4D. 1/4

Answer 1

C. 4

Step-by-step explanation:

Given the line that passes through points (-1,-7) and (3,9):

`\begin{gathered} \text{Slope},m=\frac{Change\text{ in y-axis}}{Change\text{ in x-axis}} \\ =(9-(-7))/(3-(-1)) \\ =(9+7)/(3+1) \\ =(16)/(4) \\ =4 \end{gathered}`

The slope of the line is 4.

The correct choice is C,
