Answer:
The equation is y = -4x
Step-by-step explanation:
In order to find the equation of the line, we need to take two points and use the slope formula. For the purpose of this, we will use (1, -4) and (0, 0)
m(slope) = (y2 - y1)/(x2 - x1)
m = (-4 - 0)/(1 - 0)
m = -4/1
m = -4
Now that we have the slope, use that and either point in point-slope form and solve for y.
y - y1 = m(x - x1)
y - 0 = -4(x - 0)
y = -4x
