Answer:
y = - 4x + 7
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 = 9 - 4x is in this form with m = - 4
• Parallel lines have equal slopes, hence m of parallel line is 4
note the line passes through the y -axis at (0, 7) ⇒ c = 7
y = - 4x + 7 ← equation of parallel line
