A) y= 2.75
B) y= 2.75x
C) y= x + 2.75
D y= 2.75x + 2.75

Answer 1

Answer:

B) y=2.75x

Step-by-step explanation:

2.75 is the amount the DVDs cost and x is the number of DVDs Fran buys. So it'll cost her 2.75 for every DVD she buys

Answer 2

The equation that correctly describes Fran lines is y = 2.75x

A linear equation is in the form:

y = mx + b

where y, x are variables, m is the rate of change and b is the initial value of y.

Let y represent the total amount for x used DVDs.

She pays 2.75 for each DVD she buys. Hence:

y = 2.75x

The equation that correctly describes Fran lines is y = 2.75x
