Question

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

Answer 1

can u tell me by looking at the equation the way it is, what the slope is ?

Answer 2

Is it -3?

Answer 3

no...the slope will be the number right before the x. Can u tell me the slope now ?

Answer 4

3

Answer 5

-2/3

Answer 6

the slope is -2/3
understand so far ?

Answer 7

Yep

Answer 8

a perpendicular line will have a negative reciprocal slope. All that means is " flip " the slope and change the sign.
examples :
slope is 4/5...perpendicular slope is -5/4
slope is -2/1...perpendicular slope is 1/2

so what is the perpendicular slope of -2/3

Answer 9

3/2?

Answer 10

correct

Answer 11

Thank you again

Answer 12

sure thing :)
