Question

Find which lines are parallel and which are perpendicular

Line a: 4x-3y = 2
Line b: y=x+2
Line c: 4y + 3x-4

Answer 1

Lines a and b are perpendicular.

Explanation:

a: 4x = 3y + 2

4x - 2 = 3y

4/3 - 2/3 = y

Slope = 4/3

b: slope = 1

c = 4y = -3x + 4

y = -3/4x + 4 /4

y = -3/4 + 1

Slope: - 3/4
