The table shows the height of a plant as it grows. Which equation in point-slope form gives the plant’s height at any time?
A table is shown with the first column labeled Time in months and contains the values 3, 5, 7, 9 from top to bottom. The second column is labeled Plant height in centimeters with the corresponding values of 21, 35, 49, 63 from top to bottom.

y – 21 = start fraction 7 over 2 end fraction(x – 3)
y – 21 = Image with alt text: start fraction 7 over 2 end fraction ( x – 3)
y – 21 = 7(x – 3)
y – 21 = 7( x – 3)
y – 3 = start fraction 7 over 2 end fraction(x – 21)
y – 3 = Image with alt text: start fraction 7 over 2 end fraction ( x – 21)
The relationship is nonlinear.
The correct equation in point-slope form is:
y - 21 = 7/2(x - 3)
