Answer:

A

Explanation:

We want to find the equation of the line in slope-intercept form.

From the graph, we are given the two points (-5, 1) and (0, -3).

We can find the slope between them. The slope formula is given by:


\displaystyle m=(y_2-y_1)/(x_2-x_1)

We will let (-5, 1) be (x₁, y₁) and (0, -3) be (x₂, y₂). Substitute:


\displaystyle m=((-3)-(1))/((0)-(-5))

And evaluate:


\displaystyle m=(-4)/(5)=-(4)/(5)

Next, notice that the point (0, -3) is already the y-intercept, so we do not need to find it.

Slope-intercept form is given by:


\displaystyle y=mx+b

Therefore, our equation is:


\displaystyle y=-(4)/(5)x-3

Our answer is A.
