Question

Need answer fast please. Which line is perpendicular to y = x + 2 and passes through (4,-1)?

y = -x+1
y = -x + 3
y = -x + 2
y = -x +4

Answer 1

C. y = -x + 3

Explanation:

y = x + 2

Find perpendicular slope (opposite reciprocal):

x/1 --> -1/x or -x

Convert to point-slope form:

y - (-1) = -1 (x - 4)

y + 1 = -1x + 4

y = -x + 3
