Answer:
C
Step-by-step explanation:
The simplest way to solve this problem is plugging the X value back into each equation. C (y=4x+1) is the only equation that works for each set. You plug in 1 for X, you get 5 for Y. You plug in 4 for X, you get 17 for Y. Etc.
-x - 2530
5x - 2530 - 6x
5x - 6x = -x
it is possible to draw a triangle with angles 90 degree, 60degree and again 60 degree
