Make up a story that can be represented by y = 3.5x.
1. Heres the graph : https://www.desmos.com/calculator/rdw0easlxd
2. In the form y = mx ...... the slope = m = 3.5
This means that as x changes by 1, y changes by 3.5
3. Suppose that it costs 3.50 to rent a canoe for 1 hour
Then...the cost of renting a canoe for x hours = y = 3.5x where y is the total cost
