Answer
(a) $1100.
(b) 12 gigabytes.
(c) increases.
Work Step by Step
Hard drive capacity in gigabytes is plotted on the x-axis and price in dollars on the y-axis.
(a) When we draw a horizontal line from the point that has an x-value of 8, it crosses the y-axis at 1100.
So, the price of the laptop with hard drive capacity of 8 gigabytes is \$1100.
(b) When we draw a vertical line from the point that has a y-value of 1200, it crosses the x-axis at 12.
So, the hard drive capacity of \$1200 laptop is 12 gigabytes.
(c) As the plotted points go up from left to right, the price of the laptop increases as the hard drive capacity increases.
