Answer:
x1 = -4
y1 = 2
x2 = 0
y2 = 3
m = (y2 - y1) / (x2 - x1)
Plug in the numbers and evaluate m, then either of the 2 equations below represents the line in point slope form:
y - y1 = m(x - x1)
y - y2 = m(x - x2)
Plug in the numbers. The slope intercept form is
y = mx + b
b = 3 (given)
m = result from earlier step
You convert to standard from and finish from here.
