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

Answer: -6/5</h3>
Explanation:
The blue diagonal line goes through the two points (0,2) and (5,-4). These are shown as the dark blue enlarged points. You can pick any other points you want that are on the diagonal line, though these are the easiest as they stand out the most.
Use the slope formula to find the slope through these points
m = (y2-y1)/(x2-x1)
m = (-4-2)/(5-0)
m = (-6)/(5)
m = -6/5
The negative slope means the line goes downhill as you move from left to right along the diagonal line.
Answer:
62.9
Step-by-step explanation:
Answer:
The unknown is 100
Step-by-step explanation:
A straight line is 180 degrees
We have two angles x, and 80
x+80 = 180
x = 180-80
x= 100
