Answer:

C.

Step-by-step explanation:

Given the points (0,7) and (4,-13)

We calculate the slope using the formula below:


\text{Slope}=\frac{Change\text{ in y-axis}}{Change\text{ in x-axis}}

Substituting the points, we have:


\begin{gathered} \text{Slope}=(-13-7)/(4-0) \\ =(-20)/(4) \\ =-5 \end{gathered}

The slope of the line is -5.

The y-intercept is the value of y when x=0

Therefore, the y-intercept is (0,7).
