How it works
A table, a graph and an equation can all show the same steady change.
d = 6t means every hour adds 6 miles.
If the cost is 9 dollars for each ticket, the cost is 9n for n tickets.
Worked examples
Read the equation
- Mia bikes with d = 6t, where t is hours.
- In 3 hours: 6 × 3 = 18.
- She bikes 18 miles.
Find the equation
- Each ticket costs 9 dollars. n is the number of tickets and c is the cost.
- Each ticket adds 9.
- c = 9n.
Plot a point
- Ava earns 3 dollars an hour. At 2 hours she has 6 dollars.
- Plot 2 across and 6 up.
- Every hour adds 3 up.
