Answer:
Horse B and has a constant rate of 11
Step-by-step explanation:
to solve for constant rate is quite simple all you have to do is solve for y over x (also known as y divided by x.)
Horse A: take any point i took (2,12) now divide 12 divide by 2 is 6 so horse A's constant rate is 6!
Horse B: Use the point given which is (10,110) 110 divided by 10 is 11.
now compare 6 < 11 therefore, horse B has a greater constant rate.
