Write a linear equation for the relationship shown by the graph. Use your equation to predict the height of the bamboo plant after 7 days.

The height y in centimeters of a second bamboo plant is given by the equation y = 30x, where x is the time in days. Describe how the graph showing the growth of this plant would compare to the graph showing the growth of the first plant.

Maria graphed the linear equation y = x + 3. Then she used her ruler to draw a vertical line through the point (4, 0). At what point do the two lines intersect?

Antonio claims the linear equation for the relationship shown by the graph is \(\text{y} = \cfrac{1}{2}\text{x} + 2\). Use numbers and words to support Antonio’s claim.
