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

Answer 1

Here Plant height = 5 * time

i.e. y = 5x which is the required equation.
