A) y=4x
B)  y=-4x-2
C) y=4x+2
D) y=-4x+6
E) y=-4x-6

Quizplus · Accepted Answer

The equation of a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept. We are given the point (2,-2), which means that x=2 and y=-2. We are also given that the slope is m=-4. Substituting these values into the slope-intercept form gives us:
-2 = (-4)(2) + b
-2 = -8 + b
b = 6
Therefore, the equation of the line is y = -4x + 6, which is option D.
