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.
