The Dallas Zoo recently celebrated the birth of two twin brown bear cubs named Mish and Mash. Each cub was weighed each week since birth. Mish\'s weight was recorded on a table and Mash's weight was graphed on a coordinate plane.

Question

Mish
y=4x+1

mash

y=3x+2

Which bear cub was heavier at birth and by how much?

A. Mish was heavier by 1 poundMish was heavier by 1 pound

B. Mish was heavier by 2 poundsMish was heavier by 2 pounds

C. Mash was heavier by 1 poundMash was heavier by 1 pound

D. Mash was heavier by 2 pounds

Answer 1

To determine which bear cub was heavier at birth, we can compare the y-intercepts of the two equations.

For Mish, the y-intercept is 1.

For Mash, the y-intercept is 2.

Since Mash's y-intercept is greater, Mash was heavier at birth by 2 pounds.

Therefore, the correct answer is D. Mash was heavier by 2 pounds.
