The x-intercept is
The y-intercept is
Intercepts are points where a graph crosses the x and y axis.
For a linear equation, like your problem, it is very easy to locate these two points. First the x-intercept can be found by substituting "0" in place of the "y" in your equation.
In the same way, you can calculate the y-intercept by substituting "0" in for the "x" variable in the equation.
