Answer:
Step-by-step explanation:
x-the original price
y- the discounted price
y= the original price - 25 % discounted from x = x- (.25*x) = x( 1-.25) = .75x
equation is y= .75x
The equation should only be in the first quadrant because the prices can only be positive numbers.
Because you have to connect the other two sides , so a diagonal line will be longer than a vertical line
Answer:

9x1/2=4.5
4.5x2=9
30.
15x15=225
