part b

1. which of the following lines of best fit represent the data if x is the number of days since the plant appeared and y is the height of the plant?

a. y = –3.5x + 0.7 wrong

b. y = –0.7x + 3.5 wrong

c. y = 0.7x + 3.5 wrong

d. y = 3.5x + 0.7 correct

2. explain why your choice of equations best fits the data. explain what the slope and y-intercept of the line of best fit mean about the bamboo plants.

part c

use the line of best fit chosen in part b to predict the height of a bamboo plant 40 days after appearing above the soil. show your work.

Look at this system of equations. -3x + 3y = 12 y = x + 4 the solution set of this system is best explained by which of these statements? a) the graphs of the equations are the same line because the equations have the same slope and the same y-intercept. the system has infinitely many solutions. b) the graphs of the equations are parallel lines because they have the same slope but different y-intercepts. the system has no solution. c) the graphs of the equations are lines that intersect at one point because the equations have the same slope but different y-intercepts. the system has exactly one solution. d) the graphs of the equations are lines that intersect at one point because the equations have the same slope and the same y-intercept. the system has exactly one solution.
