Answer:

Explanation:

If we have two points, we can use point-slope form to write an equation

y-y1 = m(x-x1)

But first, we need to find the slope with the formula y2-y1 / x2 -x1

-4 + 1 / 3 + 2

m = -3/5

now we can use the point slope formula.

y-y1 = m(x-x1)

substitute one of the points for y1 and x1.

here I will use (3,-4).

y+4 = -3/5 (x-3)

y + 4 = -3/5x + 9/5

y + 20/5 = -3/5x + 9/5

y= -3/5x -11/5

Hope this helps!
