Question

Tree A started at 5 feet and grew at a rate of 2 feet per month. Tree B started at 8 feet and grew at a rate of 3 feet per month.

Directions: Write a system of equations. DO NOT SOLVE

Answer 1

Tree A equation: y = 2x + 5. Tree B equation: y = 3x + 8.

Explanation:

The rate at which the tree's grow each month is m (y=mx + b) and the starting length of the trees is b (y=mx+b). Once you know those values plug them into the equation.

Answer 2

Explanation:

5 + 2x = y

8 + 3x = y
