  1. Determine The Graph of a Function

    Graph the following functions using the X-int & Y-int

    1. y=2x+7y = 2x + 7
    2. 3y=5x−63y = 5x - 6
    3. y=23x+4y = \frac{2}{3}x +4
  2. Determine The Graph of a Function in Standard Form

    Graph the following functions using the x- and y-intercepts:

    1. −2x+3y=6 -2x+3y=6
    2. x−y=4 x-y=4
Topic Notes
?
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=0y=0 into the equation.

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