Question

Sherlock wants to rent a textbook. He has to pay a fixed base cost plus a daily rate for renting the textbook. The table shows the amount of money, y, in dollars, that Sherlock has to pay for renting the textbook for x days:

Textbook Rental

Number of days
(x) Rent (dollars)
(y)
0 6
1 13
2 20
3 27
4 34
Which equation best shows the relationship between x and y? (1 point)

a
y = x + 13

b
y = 7x + 13

c
y = x + 6

d
y = 7x + 6

Answer 1

D

Explanation:

Y=kx+n

The table says when x=0 y=6 which means

N=6

Now we need k.

13=k*1+6

K*1=7

K=7

Y=7x+6
