PLEASE help!!

Answer 1

The table below shows the distance a runner is from the finish line during a race:

Answer 2

Whats your question?

Answer 3

this

Answer 4

I see information and a table, but no question

Answer 5

Write a linear equation that models the relationship between time and distance. Use mathematics to explain how you determined your equation. Use words, symbols or both in your explanation.

Answer 6

Notice how as t increases by 4, the distance decreases by 30

Answer 7

so the slope is -30/4 = -7.5

this means that the distance is shrinking by 7.5 ft per second

Answer 8

but I cant use decimals when I write a slope

Answer 9

then keep it a fraction and reduce as much as possible

Answer 10

-30/4 = -15/2

Answer 11

y = mx + b

y = (-15/2)x + b ... plug in the slope we found m = -15/2

270 = (-15/2)(4) + b

270 = -15*2 + b

270 = -30 + b

Solve for b
