ALG Slope

Quizizz expectations

• Answer every question

• If i see that you have missed 3 questions in a row i may remove you from the Quizizz, slows down the process too much

• Watch the videos in Google Classroom

• Try your best to listen and learn, i will help along the way

• Try to get better than half the questions correct

• A makeup Quizizz will be posted later today for those that miss class or haven't followed these directions

SLOPE

The constant ratio change along any line

RISE/RUN: change in y values divided by change in x values

Count the rise in y, divide by the run of x

Always start with the leftmost point
