Which best describes the polygon whose vertices in the coordinate plane are (-2, 3), (2, 3), (2, -1), (-2, -1)?
A square
Here's the four points graphed and connected by lines:
graph{((x+2)^2+(y-3)^2-.1)((x-2)^2+(y-3)^2-.1)((x-2)^2+(y+1)^2-.1)((x+2)^2+(y+1)^2-.1)((y-0x-3)(y-0x+1)(x-0y-2)(x-0y+2))=0 [-10, 10, -5, 5]}
We have a rectangle:
Do we have a square? Are all the sides the same length? Yes - they are all 4 units long.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- Is #y=5/2x# a direct variation and if so, how do you find the constant?
- How do you find the x and y intercept of #6x + 4y = 12#?
- How do you write #2x + y = 5# into slope intercept form?
- How do you find the slope of the line passing through the points (0, 5) and (-2, -1)?
- How do you find the slope and y intercept for #y = 5 – 1/2x#?
