Answer:
C.
Step-by-step explanation:
The perpendicular line will have a slope that is the opposite reciprocal of the slope of the given line. The given line equation is written in slope-intercept form ...
y = mx +b . . . . line with slope m and y-intercept b
so you can see that its slope is m=2.
The perpendicular line will have a slope that is ...
m' = -1/m = -1/2
So, you are looking for a graph with a shallow down-hill gradient, as seen in choice C. Its "rise"/"run" is down 1 for 2 to the right, so is -1/2, as needed.
