Question

Please help! (winter break)

Scenario: You planted a tree in early spring. When you planted the tree it was ___ feet tall. The tree grows at a constant rate at ___ feet a month.

X represents:
Y represents:

1. What is the y-intercept and what does it mean in the context of the problem?
2. What is the slope and what does it mean in the context of the problem?

Answer 1

When you planted the tree, it was 2 feet tall. The tree grows at a constant rate of 0.5 feet a month.

X represents: The month

Y represents: The height of the tree

1. The y-intercept is 2

2. The slope is 0.5

Explanation:

We see that when you planted the tree is when x = 0, and we see that it says y = 2, so it is the answer for your first blank. We see that the y increase by 2 when the x increase by 4, so it is 0.5 feet a month; that is the answer for your second blank!

X represents the month, Y represents the heigh!

1. Y-intercept is when the x = 0, and we see when x = 0, y= 2, so the y-intercept is 2

2. Slope is 0.5
