Question

Sara and three of her friends use an Internet mapping application to map the location of each of their houses. Sara’s house is located at (–2, –5), Nate’s house is located at (–2, 2), Michelle’s house is located at (4, –5), and Joshua’s house is located at (x, y).

(a) On your own paper, plot the three points representing Sara’s, Nate’s, and Michelle’s houses.

Answer 1

The x axis is the horizontal line where you'll count the first number in the ordered pair.
If the number is negative count to the left, if it's positive, to the right.
The y axis is the vertical line where you'll count the second number in the ordered pair.
If the number is negative, count down, if it's positive, count up. :)

Answer 2

(b) The friends discover that the four houses are the vertices of a rectangle. What are the coordinates of Joshua’s house? Explain.

(c) Joshua wants to know how far he would have to ride his bike on a trip from his house to Nate’s then to Sarah’s, then to Michelle’s, and finally back home. Use the appropriate mathematical formula to determine the distance in coordinate units that Joshua would have to ride. Show your work.

(d) Joshua knows that 1 unit on the graph represents 3 mi. He says he can multiply the perimeter of the rectangle in units by 3 to calculate the perimeter in miles. Is Joshua correct? Explain why or why not.
