Question

Identify an equation in point-slope form for the line perpendicular to y = 1/4 that passes through (-2, -6)

Apex: A. y + 2 = -4 (x + 6)
B. y - 6 = 1/4 (x - 2)
C. y + 6 = -4 (x + 2)
D. y + 6 = -1/4 (x + 2)

Answer 1

Perpendicular lines, slope is opposite and reciprocal

so slope of new line = - 4

passes through (-2, -6) in point-slope form

y + 6 = -4(x + 2)

Answer is C. y + 6 = -4 (x + 2)
