Question

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.

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.
