Answer:
- 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 3x + 9 ← is in slope- intercept form
with slope m = - 3
Parallel lines have equal slopes, thus
y = - 3x + 4 ← is the equation of a parallel line

x = 1/2 or x = -4
Since the product equals zero, use the zero product rule.
(2x - 1)(x + 4) = 0
2x - 1 = 0 or x + 4 = 0
2x = 1 or x = -4
