Question

On a coordinate plane, a line goes through points (1, negative 1) and (2, 4).
This graph displays a linear function. What is the rate of change?

Answer 1

Answer: 5

Step-by-step explanation:

(1,-1) and (2,4)

Rate of change is formulated as y2-y1/x2-x1

1 is x1

-1 is y1

2 is x2

4 is y2

plug it in

4-(-1)/2-1

two negatives makes a positive, therefore we get

5/1 =
