B. Yes, because as x increases, y also increases
X Y
1 5 (1 x 5)
2 10 (2 x 5)
3 15 (3 x 5)
5 25 (5 x 5)
I used a graphing calculator for this.
The solution my calculator got was:
(-2.625, 0.688) My calculator is very accurate, I don't think the test expects it to be like that.
Let's find the closest coordinates.
"B" is the closest.
I hope this helps!

A, C, and E.
you can check them by putting into y=mx+b form. if m is negative then as domain increases range decreases.
2/3 and 12/18 are equivalent fractions, and 12+18 = 30 so the answer is 12:18
