Ineed the equation of the line in the graph

x + y = 16 and x = y + 3.

Step-by-step explanation:

Let us assume that in that particular game, Serenity has made x number of two-point shots and y number of three-point shots.

Given that, Serenity scored a total of 16 points and made 3 more two-point shots than three-point shots.

Hence, we can write the system of equations from the above conditions as

x + y = 16 and x = y + 3.

So, those are the system of equations that can be used to get the value of x and y. (Answer)
