Let's return to Trisha's two plants. The table gives the height of each plant over two weeks. Earlier, you determined how long it would take the plants to be the same height by plotting points and graphing lines to represent a system of equations. The point of intersection was the solution to the system. This time, you'll find the solution algebraically. Plant A Plant B Weeks Height (inches) Weeks Height (inches) 0 6 0 4 2 8 2 7 Part A What are the slope and the y-intercept of the line that represents plant A's height in inches in terms of the number of weeks? (Hint: The formula for slope is slope = rise, and the y-intercept is the y-coordinate when x = 0.)
