Question

i need help how to find the x and y intercepts for these slope. Here are the questions:
1) x+2y=8
2) 2x + 2y +-4
3) 3x + y = 12
4) 2x + 4y=-4

Answer 1

So first we need to know exactly what an x and y intercept is. An x intercept is the value of x when y = 0. This makes sense because it touches the x axis at this point. So with this we can look at the first problem...

Answer 2

\[x + 2y = 8\] Let's set y=0 and solve for x to find the x intercept.
\[x + 2(0) = 8\]
So x = 8. if you have a graphing calculator you can check this too!
------------------------
For y intercept we set x=0.
\[x + 2y = 8\]
\[0 + 2y = 8\]
\[y = 4\]
