Answer:
y = -3x + 12
Step-by-step explanation:
The slope of parallel line is the same as the original line.
If the x-intercept is 4, this as a point can be stated as (4, 0)
We can now solve for the y-intercept.
y = -3x + b
0 = -3(4) + b
0 = -12 + b
12 = b
Put everything we solved for back into the formula [ y = mx + b ]
y = -3x + 12
Best of Luck!
