Hayley, I think you messed this one up.  sad

Nevermind, you have post heaps of really good answers.   laugh

 

Find the y-intercept and the x-intercept for the equation.

3x+4y=48

 

What is the y-intercept?  x=0

so

4y=48

y=12

 

What is the x-intercept? y=0

so

3x=48

x=16

Simplifying 3x + 4y = 48

Solving 3x + 4y = 48

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-4y' to each side of the equation.

3x + 4y + -4y = 48 + -4y

Combine like terms: 4y + -4y = 0

3x + 0 = 48 + -4y

3x = 48 + -4y

Divide each side by '3'.

x = 16 + -1.333333333y

Simplifying x = 16 + -1.333333333y

But what is the y-intercept and the x-intercept

X Intercepts put y =0 
3x =24 
x=8 (8,0) 

Y Intercepts put x=0 

-4y=24 
y= -6 (0,-6) 

Slope Intercept form y=mx+b 
-4y=24-3x 
y = -6 +3/4 x 
y = 3/4 x -6 

 

So.. Basically ..

y=0

x=8

making it..

(8,0)
