Answer:

The slope is 24

Step-by-step explanation:

Use any two points in the graph to find the slope of the graph
- - - - - - - - - - - - - - - - - - - -
Step 1. Use two points

Ex: (10, 320) & (5, 200)

Step 2. Find the slope using the two points

m = slope

m = change in y/change in x

m = (y2 - y1)/(x2 - x1)

m = (200 - 320)/(5 - 10)

m = -120/-5

m = 120/5

m = 24

The slope of the graph/line is 24

A track has the shapes shown. what is the perimeter ?

USPshnik [31]

Break this problem down first. You have two lines each with length of 5. You also have two halves of a circle, combine them to get a full circle with a radius of 2. The formula to find the perimeter of a circle is
$2\pi \times r$
and this gives a perimeter of 12.566 for the circle. Add this to your sides and you get a total of 22.566 which is answer B
