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)

2 16

4 32

6 48

8 64

Ay – 16 = 8(x – 2)
By – 16 = 8x – 2
Cy + 16 = 8(x + 2)

D.The relationship is nonlinear.

Answer:

Option A is correct.

\(y-16=8(x-2)\) is the equation represent the point slope form gives the plant's height at any time.

Step-by-step explanation:

Point slope intercept form: For any two points \((x_1, y_1)\) and  \((x_2, y_2)\) then,

the general form

\(y-y_1=m(x-x_1)\) for linear equations;  where m is the slope given by:

\(m =\frac{y_2-y_1}{x_2-x_1}\)

Consider any two points from the table;

let A= (2 , 16) and B =(4, 32)

First calculate the slope of the line AB:

\(m =\frac{y_2-y_1}{x_2-x_1}=\frac{32-16}{4-2}=\frac{16}{2}\) = 8

Therefore, slope of the line m = 8

Then,

the equation of line is:

\(y-y_1=m(x-x_1)\)

Substitute the value of m=8 and (2, 16) above we get;

\(y-16=8(x-2)\)

Therefore, the equation in point slope form which gives the plant's height at any time is; \(y-16=8(x-2)\) , where x is the time(months) and y is the plant height (cm)
