Question

What is the x-intercept in this linear equation?
How do I find it?

2y - 4x = -12

Answer 1

the x axis is the y=0 axis; so the x axis is intercepted (gets crossed) when y=0

Answer 2

1. re-arrange for y=stuff, solve for y
\[2y - 4x = -12 \rightarrow 2y=4x-12 \rightarrow y=2x-6\]
2. when y=0, that is when the output of the function is zero, that's when you'll intercept the x-axis

Make sense?

Answer 3

Yeah, thanks guys.
