Question

what is the slope of the line passing throught the point (3, -4) and perpendicular to the line y=3x+5?

Answer 1

The slope of y = 3x+5 is 3 or 3/1

Flip the fraction and flip the sign to get -1/3

Answer 2

This is the slope of any line that is perpendicular to y = 3x+5

Answer 3

right, so it would be 3?

Answer 4

no

Answer 5

-1/3 because 3 is the original slope, -1/3 is the perpendicular slope

Answer 6

the slope is -1/3?

Answer 7

the slope of the perpendicular line is -1/3, yes

Answer 8

Plug into the formula for the equation of a line:
(y+4)=(-1/3)(x-3)
= y+4=(-1/3x+1)
y=-1/3x-3
