Answer:
y = 2x -4
Step-by-step explanation:
The coefficient of x in the given equation is the slope of the line. A perpendicular line will have a slope that is the opposite reciprocal:
-1/(-1/2) = 2
The point-slope form of the equation of a line can be used to find the desired equation:
y -y1 = m(x -x1) . . . . . . line through (x1, y1) with slope m
For (x1, y1) = (2, 0) and m = 2, the equation is ...
y -0 = 2(x -20
y = 2x -4
