Answer
y + 3 = -3(x-8)
y=-3x+21
Work Step by Step
The equation can be rewritten as: y = -3x + $\frac{9}{4}$
Since the line must be parallel to this one, the slope (-3) must also be the same. Since we now have a point (8, -3), and the slope, we can use point-slope form to get:
y+3=-3(x-8) or y=-3x +21
