10. Problem-Solving Practice:

11. PROBlem-solving practice!
Mrs. Fisher started growing Apple trees on her farm. She measured the height of 5 of the trees when she started and every two years measures them again. She found that the average height of the trees can be described by the equation y=4x + 36, where y is the average height in inches and x is the age of the tree.
Make a table of values that shows the estimated heights
or the trees when they are 6, 7, 8, 9, and 10 years old.
Use the equation below.
Y= 4x + 36

12. Graph the Values on a coordinate Plane. Make sure to label!!!
Mrs. Fisher started growing Apple trees on her farm 20 years ago. She measured the height of 5 of the trees when she started and every two years measures them again. She found that the average height of the trees can be described by the equation y=4x + 36, where y is the average height in inches and x is the age of the tree.

Mrs. Fisher started growing Apple trees on her farm 20 years ago. She measured the height of 5 of the trees when she started and every two years measures them again. She found that the average height of the trees can be described by the equation y=4x + 36, where y is the average height in inches and x is the age of the tree.
Can the graph you created be used to determine whether the height of the trees at 20 years old? Explain.

She found that the average height of the trees can be described by the equation y=4x + 36, where y is the average height in inches and x is the age of the tree.
The program Mrs. Fisher used to track the ages and heights was damaged and only the heights below can be seen. This is the data that remains: 86, 95, 98, 102, 104, 106 Can you estimate the age of the trees with this data? If so, give the ages and show your work. Explain your thinking.
