draw a horizontal line at y=2
draw a vertical line at x=5
draw a sloping line from the origin, where every point y=x. For example, 5,5 is on this line, as is 3,3
graph each set of lines to form a triangle. find the area and perimeter.
y=2, x=5 , and y=x
Answer is Area = 4.5 units Perimeter = 6 + square root of 2.
I don't know how to graph this. What does y=x mean?
