Answer:
a
Explanation:
If a line is parallel to the given line, then you know it must have the same gradient, because that is what parallel means. So the incline must also be -2.
From this alone, you now only have to choose between answers a and b.
The parallel line had a general form of y = -2x + b
b is the intercept with the y-axis
substitute the point that is on the parallel line and solve for b
y = -2x + b
b = y + 2x
substitute the values of (4, 0)
b = 0 + 2(4)
b = 8
y = -2x + 8 which is answer a.
