Constant Rate of Change

Time (sec) Number of bottles EX1)The chart shows the number of bottles filled in a factory. Use the information to find the approximate constant rate of change in bottles per second The machines constant rate of change is 5 bottles in one second ratio = bottles/seconds

EX2)The graph represents the cost of tickets in a carnival. Determine the constant rate of change of cost per ticket. (2,3) (4,6) (6,9) The cost is $1.50 per ticket Step 1 Find the coordinates of two points on the line. Step 2 Find the change of the two points Step 3 Simplify y x (y) (x)

Essential Question How can you determine the unit rate on a graph that goes through the origin?
