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

Line C is perpendicular to both A and D.

Step-by-step 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

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
