Slope and Y-Intercept

SLOPE

Lets Review: SLOPE is....

• which direction a line moves

• how fast it moves

• Count the rise/over run​

• Divide y/x

Multiple Choice

Y-Intercept​

Let's Review: Y-Intercept

​- Moves the line up and down the y-axis

• - you can find the inercept by: y-x

• - the slope is 1
