Step-by-step explanation:
Given that:

Cost per pound of apple = $3.75
Cost of 2 pounds of raspberry = 3 * $3.50 = $10.50
Cost of 2 pounds of apple = 2 * $3.75 = $7.50
Total spent = $(10.50 + 7.50) = $18.00
Cost of X pounds of raspberry and Y pound of apple

(3.50 * X) + (3.75 * Y)
3.50x + 3.75y

Over the x-axis: (x, y) (x, –y)
Over the y-axis: (x, y) (–x, y)
Over the line y = x: (x, y) (y, x)
Through the origin: (x, y) (–x, –y)
