Question

Graph 3x+4y=-12

Answer 1

3x+-12=4y

divide all others by four to get y=3/4+-3

Answer 2

I mean 3/4x+-3

Answer 3

something like that

Answer 4

I hope this helps you understand HOW it works.

Answer 5

Change into Slope-Intercept form. Then graph.

Slope-intercept form:
y = mx + b
m is slope
b is y-intercept (where the line crosses the y-axis)

3x+4y=-12
Subtract 3x from both sides.
4y = -3x - 12
Divide both sides by 4.
y = -3/4x - 3

So you have a slope of -3/4 and a y-intercept of -3.

To graph you need to have that^

FIRST, plot the y-intercept(-3) which would be point (-3,0)
NOW remember that:
Slope=riserun=−34

So from point (-3, 0), you RISE first...its a -3 so you go down 3 spaces. Next go 4 spaces to the right (RUN).

Plot the point. Connect the two points.

And theres your graph. (:
