Question

A line has this equation: y = x + 4 Write an equation for the perpendicular line that goes through (2, 5).​

Answer 1

y = -x + 7

Explanation:

y = x + 4 slope: 1

slope of perpendicular line: -1

for (2,5) y interception (b) = y - mx = 5 - (-1)*2 = 7

equation: y = -x + 7

check: -x+7 = -2+7 =5
