Question

A linear function contains the following points. 0,74,-13What are the slope and y- intercept of this function?

Answer 1

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).
