Question

Look at this graph: What is the slope? Simplify your answer and write it as a proper fraction, improper fraction, or integer.​

Answer 1

1/2

Explanation:

Pick two points on the graph that are easy to read. A point is easiest to read if it lies on the intersection of grid lines.

For example, pick (10, 50) and (30, 60) which are easy to read.

slope = rise/run

rise = change in y

run = change in x

To go from (10, 50) to (30, 60), you go 20 units right. "20 units right" is a change of +20 units in x. The run is 20.

To go from (10, 50) to (30, 60), you go 10 units up. "10 units up" is a change of +10 units in y. The rise is 10.

slope = rise/run = 10/20

slope = 1/2
