Question

The table shows the age and height of a student over time.

 

Age (yr), x	Height (in.), y
8	51
9	53
10	55
11	57

 

Determine the slope of the data in the table.

 

m= __

Part B

Interpret the meaning of the slope in the table.

Answer 1

set up two points to find the slope (9,53) and (10,55) then do y2-y1->55-53=2 and x2-x1-> 10-9=1 or due to y/x the slope is 2/1 or just 2 which means that the children grow 2 inches every year
