Slope-Intercept Form and Graphing

The y intercept is AWESOME! It helps us to know...

• Where our line will end.

• If our line is positive or negative.

• Where to start graphing our line.

When graphing, what do you do after you graph your y-intercept?

• Find slope and start with your run(left or right) then to rise (up or down)

• Find slope and start with your rise (up or down) then to run (left or right)

• Draw a vertical line

• Draw a horizontal line
