The graph shows the height, y, in centimeters, of a plant after a certain number of weeks, x. shania drew the line of best fit on the graph.

a graph titled plant height shows number of weeks on x axis and height of plant in cm on y axis. the scales on both x and y axes are shown from 0 to 5 at increments of 5. the graph shows dots at the ordered pairs 0, 1 and 0.5, 1.2 and 1, 1.4 and 1.5, 2 and 2, 2.4 and 2.5, 2.7 and 3, 3 and 3.5, 3.3 and 4, 3.5 and 4.5, 3.8 and 5, 4. a straight line joins the ordered pairs 0, 1 and 5, 4

what would most likely be the approximate height of the plant after 7 weeks?

5.2 centimeters
7.6 centimeters
8.7 centimeters
12.7 centimeters

5.2 cm.

Step-by-step explanation:

Given :

Number of Weeks(x)     Height of Plant (y)

 0                                          1

0.5                                       1.2

  1                                         1.4

 1.5                                       2

  2                                        2.4

 2.5                                      2.7

  3                                        3

 3.5                                      3.3

  4                                        3.5

 4.5                                      3.8

  5                                         4

We are given that A straight line joins the ordered pairs 0, 1 and 5, 4

So, we will find the equation of line using two point slope form:

Substitute the values in the formula

---A

Now we are supposed to find e the approximate height of the plant after 7 weeks.

Substitute  x = 7 in A

Hence  the approximate height of the plant after 7 weeks is 5.2 cm.
