Answer:
C. plot a point at the y-intercept
Step-by-step explanation:
I'd start with setting up the equations. Calling x the number of students in most popular country 1, and y in country 2.
x + y = 44740
x - y = 5672
now solve for x1 and x2. You can subtract second from first:
0 + 2y = 39068
y = 19534
so
x = 5672 + 19534 = 25206
Add a sentence to answer it in words.
-10/5 or -8/4
You can make up an equation with the solution of -2 by multiplying -2 by any number ( for example -2 x 5 ) and then divide the result by the random factor you chose ( which would be 5 in this case )
