Question

What is the equation of the line described below written in slope-intercept form?

the line passing through point (2, 2) and perpendicular to the line whose equation is y = x

y = x - 4
y = x + 4
y = -x + 4

Answer 1

Judging on the question I figured that the perpendicular line's slope would be -x since the slope of a perpendicular line is opposite to that of a the reference line.

Thus, your answer should be y=-x+4 considering that is the only equation with the slope of -x.

Answer 2

y=-x+4 is the answer!!!
