We are going to want to put this into slope-intercept formula. But first we need to find the slope
(5, 3) (25, 19) (19-3)/(25-5) 16/20 4/5 = m
We then put this into the formula. But now we have to find b by plugging in one of the points as x and y. y = 4/5x + b (10,7) 7 = 4/5(10) + b 7 = 8 + b -1 = b Our equation will be y = 4/5x -1.
Then we can plug in 40 as x to find the plant's height
