In 4 and 5, find the missing coordinates and tell what the point represents. A coordinate plane labeled “Comparing Temperature Change in Metals” that has the x-axis from 0 to 1,800 and the y-axis from 0 to 1, 700.

The x-axis is labeled “Titanium (degrees Celsius)” and the y-axis is labeled “Aluminum (degrees Celsius)”. A line starts at (0, 200) and goes to the point (1,700, 1,400). A point labeled “(300, 400)” is at the 300 on the x-axis and the 400 on the y-axis. A point labeled “(600, 600)” is at the 600 on the x-axis and the 600 on the y-axis. A point labeled “(x, y)” is at the 900 on the x-axis and the 800 on the y-axis. A point labeled “(1,200, 1,000)” is at the 1,200 on the x-axis and the 1,000 on the y-axis. A point labeled “(1,500, 1,200)” is at the 1,500 on the x-axis and the 1,200 on the y-axis.
A coordinate plane labeled “Yosemite Wildlife Sightings” that has the x-axis from 0 to 800 and the y-axis from 0 to 800.

The x-axis is labeled “Deer” and the y-axis is labeled “Elk”. A line goes through the following points. A point labeled “(100, 50)” is at the 100 on the x-axis and the 50 on the y-axis. A point labeled “(x, y)” is at the 200 on the x-axis and the 150 on the y-axis. A point labeled “(300, 250)” is at the 300 on the x-axis and the 250 on the y-axis. A point labeled “(400, 350)” is at the 400 on the x-axis and the 350 on the y-axis. A point labeled “(500, 450)” is at the 500 on the x-axis and the 450 on the y-axis. A point labeled “(600, 550)” is at the 600 on the x-axis and the 550 on the y-axis.
For Exercise 5, find two other points on the line. Then graph and label them. Describe the relationship between deer sightings and elk sightings.
