Find the slope and y-intercept of the line in the graph.

slope = 3x , y intercept = 5

Step-by-step explanation: use the formula : y2 - y1 / x2 - x1 to find slope. y intercept is shown on graph

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet
