Question

The equation of line XY is (y-3) = -2/3 (x - 4). What is the slope of a line perpendicular to XY

Answer 1

what is slope of xy line ??

Answer 2

\[\huge\rm y- y_1 = m (x-x_1)\] point slope form where m is slope so what is slope of xy line ?

Answer 3

this is geometry?

Answer 4

omg this so easy... no offense

Answer 5

m=slope

Answer 6

u don't even need to calculate

Answer 7

what is slope of xy line ??
look at the point slope equation there is m which is slope
so what is m in xy equation ?

Answer 8

so if you match the number equation into the formula u can see what m is

Answer 9

yea what he/she said

Answer 10

so is it 3/2?

Answer 11

eggactly

Answer 12

YEP sope of xy is -2/3 but they are asking for perpendicular so you need to filp the fraction and change sign so yes its 3/2 :)
