### Practice: Model linear relationships with y = mx + b; determine and interpret rate of change and initial value.
Model linear relationships with y = mx + b; determine and interpret rate of change and initial value.
Work each problem. If you get it right, you will see a check and can move on. If you get it wrong, you will see exactly why and the steps to the correct answer, then you can try the next one. This practice is not graded.
