Answer:
y = 2x - 4
Step-by-step explanation:
Perpendicular lines have opposite reciprocal slopes, so the line will have a slope of 2.
Plug in the slope and the given point into y = mx + b, and solve for b:
y = mx + b
0 = 2(2) + b
0 = 4 + b
-4 = b
Then, plug in the slope and b into y = mx + b
y = 2x - 4 is the equation of the line
