Graphing linear functions using x- and y-intercepts

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.

Basic Concepts:Slope equation:

m = \frac{y_2-y_1}{x_2- x_1}

, Slope intercept form: y = mx + b,

Lessons

• 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.
