The first thing you should do in this case is to write the equation in its generic form.
We have then:
y-yo = m (x-xo)
We look for the slope:
m = (y2-y1) / (x2-x1)
m = (0-3) / (3 - (- 2))
m = -3 / 5
We choose any point of the line:
(xo, yo) = (- 2, 3)
We substitute the values in the generic equation:
y-3 = -3 / 5 (x - (- 2))
We rewrite:
y-3 = -3 / 5 (x + 2)
Answer:
b) (y - 3) = - 3/5 (x + 2)
