LINEAR FUNCTION/EQUATION: a function whose graph is a line. PARENT FUNCTION: The simplest equation of a function. The equation y=x or f(x)=x is the LINEAR PARENT FUNCTION First… the Vocabulary

 Y=mx+b  m = slope  b = y-intercept  Y-INTERCEPT: the y-coordinate of the point where a line crosses the y-axis SLOPE INTERCEPT FORM

Identify the slope and y-intercept. What will the graphs look like? y=3x+1 y=1/2x – 5 y=-2x+4 y=x Y= 2x Some examples

Now, it’s your turn to graph these equations. Draw a large coordinate graph (using a ruler) in your notebooks. We’ll walk through each one slowly. y=3x+1 y=1/2x – 5 y=-2x+4 y=x Y= 2x Graphing Linear Equations
