Answer:
k = 9
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to 8
m = ![\frac{y_{2}-y_{1} }{x_{2}-x_{1} }](https://tex.z-dn.net/?f=%5Cfrac%7By_%7B2%7D-y_%7B1%7D%20%20%7D%7Bx_%7B2%7D-x_%7B1%7D%20%20%7D)
with (x₁, y₁ ) = (- 1, 1) and (x₂, y₂ ) = (0, k)
m =
= k - 1 = 8 ( add 1 to both sides )
k = 9
There are 12 inches per foot. If the tree is 48 feet tall, it is 48 x 12 = 576 inches tall.
