Write the equation of a line in slope intercept form with a y intercept at the origin and a slope of 2

y=x+2
y=2
y=2x
2y=x

y=2x. Remember the equation is y=mx+b, M is slope and b is the y intercept. You'll need to know that for a lot of things in math going forward

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

55? i think maybe
