Question

100 POINTS

The graph shows the heights, y (in centimeters), of a plant after a certain number of weeks, x. Donna drew the line of best fit on the graph. What would most likely be the approximate height of the plant after 8 weeks?

11.0 centimeters
9.25 centimeters
8.8 centimeters
7.4 centimeters

Answer 1

Answer:

5.2 centimeters.

Step-by-step explanation:

The equation of the line is:

y = mx + b

The slope is 3/5. The y-intercept is given 1.

y = 3/5x + 1

Put x as 7, to find where point y lies.

y = 3/5(7) + 1

y = 21/5 + 1

y = 4.2 +1

y = 5.2
