Question

Line A: y = 1 2 x + 2 Line B: y = − 1 2 x + 7 Line C: y = −2x + 4 Line D: y = 1 2 x + 5 4 which lines are perpendicular

Answer 1

Answer: Line A and C.

Step-by-step explanation: Perpendicular lines must cross at right angles to each other.

Answer 2

Line C is perpendicular to both A and D.

Explanation:

Perpendicular lines have opposite and reciprocal slopes. Since C has a slope of -2, we look for lines that have a slope of 1/2, which is both A and D
