Question

Which point is a distance of 5 units from the point (1,9)?

a.) (6,8)
b.) (2,4)
c.) (3,3)
d.) (5,6)

Can someone please explain how to find the answer?

Answer 1

You just need to plot them on a graph and see how many spaces are in between each. So if you plot (1,9) remember it's X, Y axis. Start from zero on the graph. Since it's positive go over 1 to the right and up 9. Then do the same for the rest. Then count how many units are between each point on the graph and find the one that is 5 units apart.
