Renata wins a $20 gift card to an online music site. After Renata purchases 16 songs, the gift card has a remaining
amm1812

Answer: y=20-1.25x

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

y=mx+b

Where "m" is the slope of the line and "b" is the y-intercept.

You need to analize the information given in the exercise.

You know that gift card had a total of $20. Then, since she started to buy the songs with $20, you can identify that:

b=20

Since Renata purchased 16 songs and the gift card had a remaining  balance of $0 after this, you can find the cost of each song. This is:

\frac{20}{16}=\$1.25

Therefore, she spent $1.25 per song. This means that the slope is:

m=-1.25

Then, you get that the equation that represents the relationship between "y" (the remaining balance on Renata's gift card) and "x" (the number of songs purchased) is:

y=20-1.25x

Which equation(s)
GalinKa [24]

Answer:  A) y = 7x

<u>Step-by-step explanation:</u>

In order to be a proportional relationship, the equation MUST pass through the origin (0, 0) and only contain two coordinates

A) 0 = 7(0)      --->        0 = 0 TRUE

B) 0 = 2 + 3(0) --->       0 = 2 False

C) 0 = Vz(0)    --->        Too many variables so False

D) 0 = 5 - 0    --->         0 = 5 False
