1. The height, in centimeters, of Diego’s plant is represented by the equation , where represents the number of weeks since Diego has started nurturing the plant. Decide if each statement is true or false. Explain your reasoning.
   • Diego’s plant shrinks each week.
   • Diego’s plant is 8 centimeters tall when he starts to nurture it.
   • Diego’s plant grows to be 58 centimeters tall.
   • The plant shrinks 4 weeks after Diego begins to nurture it.
2. Write your own true statement about Diego’s plant.

Jada’s quiz grade after hours of studying is given by the equation . Her test grade after hours of studying is given by the equation .

Here’s a graph of both functions:

Graphs of two lines on coordinate plane. Horizontal axis, hours studied, h, by twos from negative 4 to 4. Vertical axis, grade, y, by tens from negative 20 to 100. Graphs intersect at point 1 point 5 comma 85. Black line goes through point 0 comma 70. Blue line goes through the point 0 comma 76.

1. Which graph represents Jada’s quiz grade after hours of studying?
2. What do the -intercepts of the lines mean in this situation?
3. Find the coordinates of the -intercepts.
4. The 2 lines intersect at a point. What does that point represent in this situation?
5. Find the coordinates of the intersection point. Explain or show your reasoning.
