What is x?
It is the number of years since purchase. Can this be negative?
NO! Years cannot be negative. So we disregard negative x-axis.
What is y?
It is the value of the computer at that year. A computer starts off with a positive value (y axis) and depreciates to 0 after some years. Can this be negative?
NO! At 0 value, the computer is worth nothing! There is nothing known as <em>negative </em>value. So we disregard negative y-axis.
The graph that Beth will sketch will have to be in the 1st quadrant (positive x-axis & positive y-axis).
ANSWER: Quadrant I only
A= 1/2(bh)
h=4b
50= (1/2)(b*4b)=2b^2
25=b^2
base = 5 that's your answer
height = 4xb = 4x5=20
