Help asap: Sam is riding his bike home from

the library at a constant rate. The equation below describes the relationship between the number
of minutes (x) Sam has been riding and the distance (), in miles, Sam has left to travel

O A. 3
OB

O C.

OD
21

Answer 1

3 miles

Explanation:

to find the amount of miles it is to the library you have to find how many miles it is when the minutes are zero

so when x = 0 what is y

0 + 7y = 21

7y = 21

y is 3

so that means the library is 3 miles away from his house
