The plot crosses the y-axis when x=0 and it crosses the x-axis when y=0. So by substitution of 0 for one you find the value of the other by manipulation of the equation

#### Explanation:

If you meant to ask more than just how:

When

so the y-axis intercept is at

For a strait line graph it is always at the value of the constant.

So at the x-axis intercept

So the x-axis intercept is at
