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

given the data on the problem, we can use them to identify the equation that describes the increase in plant height in time. In this case, slope is equal to change in plant height per unit time equal to (25-15)/ (5-3) equal to 10/2 equal to 5. the point slope form is y - y1 = m(x-x1). substituting, y-15 = 5 *(x-3) ; y = 5x
