Answer:

y = 3x - 10

Explanation:

Find the slope of the line by calculating the Rise/Run between any two points. I picked (-2,-16) and (4,2).

The Rise is = (2-(-16))=18

The Run is = (4 -(-2)) = 6

Rise/Run is 18/6 = 3. The slope is three:

y = 3x + b

b is the y-intercept, the value of y when x=0. b is - 10 in this graph.

y = 3x - 10 is the line of this graph.
