Hello there! :)
Answer:
y = -4x.
Step-by-step explanation:
Begin by finding the slope of the line using the slope formula:

Plug in two points on the graph. We can use the points (-1, 4) and (0, 0):

Simplify:
m = -4.
Therefore, the equation of this line in slope-intercept form (y = mx + b) is:
y = -4x.
Answer:
B
Step-by-step explanation:
To do this, you need to complete the square.

Therefore, the correct answer is choice B. Hope this helps!
