Question

Christian is training for a swimming competition He starts swimming 10 ft. from the shore to his boat The table below represents the distance from the shore. f(z), as a function of time after z minutes of swimming.

Answer 1

f(x) = 20x + 10

Explanation:

(0 , 10) ; (3 , 70)

Slope =
`(y_(2)-y_(1))/(x_(2)-x_(1))`

`= (70-10)/(3-0)\\\\= (60)/(3)\\\\= 20`

y- intercept = 10

f(x) = mx + c

= 20x + 10
