Question

How do you graph the set of ordered pairs {(-2,5), (1,3), (4,-2), (4,7)}?

Answer 1

See below

Explanation:

First, plot: `(-2, 5)` - go 2 to the left of the origin on the x-axis and 5 up on the y-axis:

graph{((x + 2)^2 + (y - 5)^2 - 0.1) = 0 [-20, 20, -10, 10]}

Next, plot: `(1, 3)` - go 1 to the right of the origin on the x-axis and 3 up on the y-axis:

graph{((x - 1)^2 + (y - 3)^2 - 0.1)((x + 2)^2 + (y - 5)^2 - 0.1) = 0 [-20, 20, -10, 10]}

Use this same method to plot the other two points in the problem.
