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; Plant Height (cm): 15

Time (months): 5; Plant Height (cm): 25

Time (months): 7; Plant Height (cm): 35

Time (months): 9; Plant Height (cm): 45
