Question

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

How does one do this??

Answer 1

Solve for y. ie. get y alone on one side.

Answer 2

Y alone on one side? @agent0smith

Answer 3

to "solve for y"
first add -4x to both sides
(that means write -4x on both sides)

Answer 4

Yes, like do algebra to get y alone...

Answer 5

the answer is Slope: −43
Y-Intercept: 4

Answer 6

you should get
4x -4x + 3y = -4x + 12 (the order does not matter)

on the left side you have 4 x's take away 4 x's . that leaves no x's on the left side

Answer 7

after you simplify the left side you get
3y = -4x + 12

now divide both sides by 3 (that means both sides and *all* terms)

Answer 8

after you do that, you match up your equation with
y = m x +b

the "m" (number in front of the "x") is the slope.
