First, let's find the slope.
Slope = (7 - (-3)) / (2 - 0) = (7 + 3) / 2 = 10 / 2 = 5
So far our equation looks like: y = 5x + b
Leta plug one of the points into our equation to find b.
-3 = 5(0) + b
Simplify.
-3 = b
The equation is: y = 5x - 3
Answer choice B is correct.

Step-by-step explanation:
Total amount of money to be shared among Neymar, Rohit Sharma and Nadal is $250
Neymar gets two parts. This means that Neymar gets 1/2 × total amount of money.
Neymar gets 1/2 × 250 = 125
The percentage will be amount that Neymar gets divided by the total amount and multiplied by 100. It becomes
125/250 × 100 = 50%
Rohit gets three parts. This means that Rohit gets 1/3 × total amount of money.
Rohit gets 1/3 × 250 = 83.33
The percentage will be amount that Rohit gets divided by the total amount and multiplied by 100. It becomes
83.33/250 × 100 = 33.33%
Nadal gets five parts. This means that Nadal gets 1/5 × total amount of money.
Nadal gets 1/5 × 250 = 50
The percentage will be amount that Nadal gets divided by the total amount and multiplied by 100. It becomes
50/250 × 100 = 20%
If the number of downloads of the standard version is x, and the high quality is x, 2.1*x+4.1*y=2761 (not 1010 due to that this is multiplied by 2.1 and 4.1, therefore representing the total amount of megabytes) In addition, there are 1010 total downloads, and it's either 2.1 MB or 4.1 MB, so x+y=1010.
We have
2.1x+4.1y=2761
x+y=1010
Multiplying the second equation by -2.1 and adding it to the first equation, we get 2y=2761-1010*2.1=640 and by dividing both sides by 2 we get y=320 downloads of the high quality version
