Question

The table shows the height of a plant as it grows. What equation in point-slope form gives the plant’s height at any time? Let y stand for the height of the plant in cm and let x stand for the time in months. time (months): 3,5,7,9 Plant height (cm): 15, 25, 35,45
A. y-15= (x-3)
B, y-15= 5(x-3)

Answer 1

Let's calculate the slope first:
m = y2-y1 / x2-x1
m = 25 - 15 / 5 -3
m = 10 /2
m = 5

Now, we know, y - y1 = m(x - x1)
y - 15 = 5(x - 3)

In short, Your Answer would be Option B

Hope this helps!
