Answer:

Step-by-step explanation:
Equation of a line is given as:
y = mx + b
Where
m is the slope
and
b is the y-intercept (y-axis cutting point)
Since we know slope is -4, we can write:
y= mx + b
y = -4x+ b
Given the point (-2,7) , we can say:
x = -2
and
y = 7
Plugging these 2 values, we can solve for b:
y = -4x + b
7 = -4(-2) + b
7 = 8 + b
b = 7 - 8
b = -1
Now, we have the equation:

Answer is D or the last choice
At first let us choose the 5 points
at x = 0, y = 0
The first point is (0, 0)

We will choose a = 1/2
The points are
(-2, -4)
(-1, -1/2)
(0, 0)
(1, 1/2)
(2, 4)
