You can put this solution on YOUR website! There are two ways you can find the x-intercept of this equation.
1) You can graph the line and see where it crosses the x-axis. See the graph below.
2) You can set y = 0 in the equation and solve for x. This would be easier.
Set y = 0
Divide both sides by 4.
The x-intercept is at (1, 0)
