Question

What is the equation of the line passing through (2, –2) and perpendicular to the line y = –x + 3 in slope-intercept form?

y = x

y = –x

y = x – 4

y = x + 4

Answer 1

two lines are perpendicular if the product of their slope is -1
first, find the slope of the line y = -x + 3, let the slope is m1
then find the slope of the line that you want to find the equation, let the slope is m2,
since the lines are perpendicular, then m1 x m2 = -1
can you find m2 ?
