I need help with this one please

Answer:
The answer to your question is: letter A
Step-by-step explanation:
First, we need to find two points of the red line, then we calculate the slope and finally, find the equation of the line.
Points:
A (0, 0) B ( -1/2, -3)
slope:
m = (y2 - y1) / (x2 - x1)
m = (-3 - 0) / (-1/2 - 0)
m = -3 / -1/2 = 6
equation
(y - y1) = m(x - x1)
(y + 3) = 6(x + 1/2)
y + 3 = 6x + 3
y = 6x + 3 - 3
y = 6x
