Question

The best fit line is given by the equation y = 0.404x - 5.18, where y represents the height of the plant above ground level, and x represents the number of days since it was planted.
What is the slope of the best fit line? What does the slope of the line mean in this situation? Is it reasonable?

Answer 1

Step-by-step explanation:

The line of best fit given:

• y = 0.404x - 5.18

It is given in the slope-intercept form:

• y = mx + b, where m- slope, b - y-intercept

The slope is this situation is m = 0.404 cm and it represents the average growth rate of the plant in one day.

It seems reasonable but without means of control it is difficult to trace the growth while still under the ground, during the first 13-14 days.
