Question

What is the slope of a the line represented by the equation 4x + 3y = 12?

How does one do this??

agent0smith · Answer

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

Y alone on one side? @agent0smith

phi · Answer

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

agent0smith · Answer

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

markkboyy · Answer

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

phi · Answer

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

phi · Answer

after you simplify the left side you get
3y = -4x + 12 

now divide both sides by 3  (that means both sides and *all* terms)

phi · Answer

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.
