A biologist has been observing a tree’s height. 15 months into the observation, the tree was 14.75 feet tall. 19 months into the observation, the tree was 15.51 feet tall.Let x be the number of months passed since the observations started, and let y be the tree’s height at that time. Use a linear equation to model the tree’s height as the number of months pass.This line’s slope-intercept equation is .30months after the observations started, the tree would be feet in height.months after the observation started, the tree would be 23.11feet tall.
