Question

What is x-intercept of the line with the equation 4×+2y=12?

Answer 1

3
to solve, plug in 0 for y

4x+2(0)=12
4x=12
x=3

Answer 2

The X-intercept is a point where the line crosses the X lines. That means it would be the point where Y=0. Then to find the X-intercept you only need to insert Y=0 into the equation. The calculation would be:

4×+2y=12
4X+ 2 (0)= 12
4X =12
X=12/4 = 3
