One of the ways to graph a linear function is by using the x-and y-intercepts. If we know any two points of a straight line, it's just a piece of cake to determine its equation and graph. In order to do that, we need to find out those intercepts by solving the function first.

• To find the x-intercept, we plug in $y=0$ into the equation.
• To find the y-intercept, we plug in $x=0$ into the equation.
