Answer:

y = -(2/5)x - (16/5)

assuming the goal is to find the equation of a line.

Explanation:

Does the question ask for a line equation that includes these two points?

If so:

Lets look for an equation of the form y = mx + b, where m is the slope and b is the y-intercept (the value of y when x is zero).

Slope, m, is the Rise/Run between two points.

(-3,-2) to (2,-4)

Rise = (-4 - (-2)) = -2

Run = (2 - (-3)) = 5

Slope = -(2/5)

The equation becomes y = -(2/5)x + b

To find b, use one of the two given points and solve for b:

y = -(2/5)x + b

-4 = -(2/5)*2 + b for (2,-4)

-4 = -(4/5) + b

b = -3 (1/5) or -(16/5)

See the attached graph.

The equation is y = -(2/5)x - (16/5)
