Graphing using slope-intercept form

Y-intercept: the y-coordinate of the point where a line crosses the y-axis.

Slope-intercept form: a linear equation of a nonvertical line written as y= mx + b where m is the slope ands b is the y-intercept.

Linear equation: an equation whose graph form a straight line.

Parent function: a family of functions is a group of functions with a common characteristics. a parent function is the simplest with these characteristics.

Linear function: a function whose graph is a line is a linear function. You can represent a linear function with a linear equation.

Linear parent function:  the simplest form of a linear function.

** y=mx+b y=2x+3 m=2 b=3 ** (2,7) (1,5) (0,3)





STEPS Step 1: Find the slope and put it into rise/run formula. Step 2: Lable the y-intercept on the graph. Step 3: Use the y-intercept as an origin point for the rise/run. Step 4: Draw the line through points and your done.

OR

Step 1: Put the formula into a table. Step 2: Plug in the numbers for x and solve y. Step 3: graph the coordinates. Step 4: draw the line through the points and your done.
