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.

Related concepts: Graphing linear functions using table of values, Graphing linear functions using various forms, Graphing linear functions using a single point and slope,

• 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.
