Answer:

y = -4/3x -2

Explanation:

You want the equation of the line through the two points (-3, 2) and (0, -2).

Slope

The slope is given by the formula ...

m = (y2 -y1)/(x2 -x1)

m = (-2 -2)/(0 -(-3)) = -4/3

Intercept

The y-intercept is the value of y when x=0. The point (0, -2) tells you that is b = -2.

Slope-intercept equation

The slope-intercept equation for the line is ...

y = mx +b

Using the values we found for m and b, this is ...

y = -4/3x -2
