Question

I need help with this one

Answer 1

She charges 20 dollars per photo

Explanation:

Pick any price on the y axis and divide by the corresponding x-value. For example, the line has a point at (60,3) so we can divide 60 by 3 to give us 20. 20 is therefore the slope of the line.

Answer 2

she charges 20 dollars per photo

for every photo it goes up by 20. you could say that the slope is 20 also.
