Answer: unit rate = 1 / 5 = 0.2 inches per day
Step-by-step explanation:
The unit rate is the ratio that describes how one quantity changes as the other changes.You can find a unit rate from a graph the same way you find the slope.
1. Choose two points on the graph to find the slope
- (0,0) and (5,1)
x₁ y₁ x₂ y₂
2. Slope = y₂ - y₁ / x₂ - x₁ (This is essentially the change in y-coordinates divided by the change in x-coordinates.
unit rate = y₂ - y₁ / x₂ - x₁
unit rate = 1 - 0 / 5 - 0
unit rate = 1 / 5 = 0.2 inches per day
