Question

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

Answer 1

y = -x + 3
y = mx +b
you have x & y solve for b

Answer 2

Uhhhhhmmm,how though?

Answer 3

y = mx +b
perpendicular slope = -1/m = -1/-1 = 1
y = 1x +b
you have (2,-2)
-2 = 1(2) +b
now?

Answer 4

y = x - 4?

Answer 5

yup
-2 = 1(2) +b
-2 -2
b = -4

y = x - 4
