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
A. y – 15 = (x – 3)
B. y – 15 = 5(x – 3)
C. y – 3 = (x – 15)
D. The relationship cannot be modeled.

Time (months)  Plant Height (cm)
3                        15
5                        25
7                        35
9                        45

The table is posted right above.

Pick any two lines and calculate the gradient. i will pick first 2 for it
m = (25-15)/(5-3)
m = 5
y-y1 = m(x-x1)
y -15 = 5( x-3)
