Additive Relationships

The table shows the relationship between x and y. What is the y-intercept, of the line passing through these points.

(a)  

Alex and Dave sell donuts. Alex earns $11 more than Dave.

Let x represent the number of donuts Dave sells.

Let y represent the total amount of donuts Alex sells.

What is the y-intercept, write answer as an ordered pair?

Write an equation in the form of $$y=mx+b$$ , to determine how much money Dave earns selling donuts.

Part 1: Sara sells lemonade at her lemonade stand. On Saturday she sold 12 cups for $9.00 On Sunday she sold 10 cups for $7.50 On Monday she sold 8 cups for $6.00 What is the rate of change, for the cost of Sara’s lemonade? Part 2: Write an equation in the form of $$y=mx+b$$  , to determine how much money Sara earns each day.
