Question

what is the equation of the line through (2,1) and perpendicular to the line through (-4,1) and (3, -2)

Answer 1

do you know slope formula ??

Answer 2

y2 - y1 / x2 - x1

Answer 3

so the slope of the perpendicular like is 3 got that but not sure about the other part of the question

Answer 4

There's another formula that could help you in this question. It's the point slope formula.

y-y1= m(x-x1)

m represents the slope and x1 is 2 and y1 is 1 since the line passes through 1,2

Answer 5

thx ill try that

Answer 6

Okay so what's the slope?

Answer 7

3??

Answer 8

use this to find slope of line
