What is the slope of the line?

The slope is 3

Step-by-step explanation:

Pick two points (0,-2) and (1,1)

The slope of the line is found by

m = (y2-y1)/(x2-x1)

    = (1--2)/(1-0)

    = (1+2)/1

    =3

33%

Step-by-step explanation:

Let's find the answer by using the following formula:

(final amount)=(initial amount)+((initial amount)*(percent increase)) so:

665=500+(500*X) where X=percent increase

Solving, we have:

X=(665-500)/500

X=0.33=33%

In conclusion, the percent increase was 33%.
