Question

What is the slope of a line that is perpendicular to the line represented by the equation 3x+4y=12?

Answer 1

-3/4

Explanation:

just took it

Answer 2

lets make the equation in y = form
3x+4y=12
subtract 3x from both sides
4y=-3x+12
divide both sides by 4
y=-3/4x+3
this lines slope is -3/4
a perpendicular line has a slope that is opposite the sign (+/-) and is flipped
the perpendicular lines slope will be 4/3
