​Slope Intercept Form

Multiple Choice

How do we remember slope?

• $$\frac{rise}{run}$$  

• $$\frac{run}{rise}$$  

• $$\frac{change\ in\ x}{change\ in\ y}$$  

Draw

If you have point on (0,3), plot where you think the next point is if the slope is $$\frac{1}{3}$$

Draw

If you have point on (0,3), plot where you think the next point is if the slope is $$-\frac{2}{3}$$

Multiple Choice

If the y intercept is 4, how do you write that as an ordered pair?

• $$\left(4,\ 0\right)$$  

• $$\left(0,4\right)$$  

• None of the above

Multiple Choice
