Take  2 points: (0, 70) (30, 80)

SLOPE FORMULA: y2 -y1 / x2 - x1

y2 - y1: 80 - 70 = 10

x2 - x1: 30-0 = 30

10 / 30

simplify: 1/3

This is a PROPER FRACTION

The slope is the ratio of the rise to the run of a graph, it is also called the rate of change. Hence, the slope of the graph given is 1/3

From the graph ; draw a right angled triangle triangle at any point on the line and take the coordinates :

  • (0, 70) ; (60, 90)

  • Slope = Rise / Run

Rise = (y2 - y1) = (90 - 70) = 20

Run = (x2 - x1) = (60 - 0) = 60

Slope = 20/60 = 1/3

Therefore, the slope of the graph is 1/3.
