Question

A school has 1560 students. Four years later, the same school has 1640 students. If there was linear growth, the slope of this line would (numerically) be 20. Explain what this means.

Answer 1

Explanation:

`y=20x+1560`

`y` = Number of students

`x` = Number of years

In four years:

`y=20(4)+1560=80+1560=1640`

Hope this helps.
