Question

The table shows the height of a tree as it grows.
What equation in slope-intercept form gives the tree's height at any time?

Answer 1

The table shows the height of a tree as it grows.
What equation in slope-intercept form gives the tree's height at any time?
Time Height
(months) (inches)
2 14
4 23
6 32
8 41

y = 9x + 2
y = 9/2x + 5
y = 9/2x
y = 5x + 9/2

Answer 2

The slope m of the graph of height against time is found from the formula:
\[m=\frac{y _{1}-y _{2}}{x _{1}-x _{2}}=\frac{14-41}{2-8}=you\ can\ calculate?\]

Answer 3

I'm still kind of confused I'm sorry :(

Answer 4

We are looking for a straight line equation of the form y = mx + b where m is the slope and b is the intercept on the y axis. The first step is to use the given data to find the slope. So as I asked before can you calculate the value of the following:
\[m=\frac{14-41}{2-8}=?\]
