Use the table to draw the graph of height(y-axis) against week(x-axis).
The graph is a straight line.
Find the gradient of the graph as the first step.
Gradient = (y2-y1)/(x2-x1)
= (17-12)/(4-2)
= 5/2
Use this gradient to find the equation of the line. Use one of the point from the table (e.g. (8,27)) and another general point (x,y).
∴5/2=(y-27)/(8-x)
5/2 (x-8) = y-27
(5/2)x - 20 = y-27
y=(5/2)x - 20 + 27
y = (5/2)x + 7
The answer is A

Answer: 0.27£
Explanation:
9 apples + 9 bananas = 2.43
9(apple + banana) = 2.43
Apple + banana = 2.43/9
Apple + banana = 0.27£
Therefore, the cost of an apple AND a banana is 0.27£
