Question

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?

Time (months) Plant Height (cm)
3 21
5 35
7 49
9 63

Choose the correct answer:
y – 21 = 7/2(x – 3)
y – 21 = 7(x – 3)
y – 3 = 7/2(x – 21)
The relationship is nonlinear.

Answer 1

2nd choice bro since the slope if you take the first ex and the last

Answer 2

you get 63-21/9-6 which is 42/6 =7

Answer 3

he meant 63-21/9-3 which is 42/6 =7
so m =7 the slope in the equation

y-y1=m(x-x1)

Answer 4

thanks both of you :)
