Answer:
D. -½
Step-by-step explanation:
Since line p and q we perpendicular to each other, thus, the slope of line q will be the negative reciprocal of the slope of line p.
Given that line p has a slope of 2, therefore, the slope of line q will be the negative reciprocal of 2.
Negative reciprocal of 2 = -½.
Slope of line q = -½.
