Question

Find an equation of a line perpendicular to the graph of 9x–3y=7 that passes through the point at (–6, 6)

Answer 1

first can u find the slope of line 9x-3y=7 ?

Answer 2

@hartnn ya its x1 y1 x2 y2

Answer 3

whats that??

Answer 4

@hartnn thats the formula

Answer 5

y=3x-7/3 is the equation in y= form

Answer 6

no it isn't...
first isolate y from that equation 9x-3y=7
and tell me what u get....

Answer 7

right,so the slope now is co-efficient of x,which is?

Answer 8

I'm not sure

Answer 9

y=-1/3x+4 is my answer?

Answer 10

the co-efficient of x is 3,so the slope is 3.
yes it is :)

Answer 11

you saw that its a negative 1/3 right? just wanna make sure so you dont approve the wrong answer lol thats happened before

Answer 12

@hartnn

Answer 13

thats correct,because slope of perpendicular lines are negative reciprocal

Answer 14

thanks!

Answer 15

welcome :)
