Question

Point D is located at (-1, 3). What is the coordinate of E if the length of DE is 10 units? Write your answer as an ordered pair with no spaces.

a) (9, 3)

b) (-11, 3)

c) (-1, 13)

d) (-1, -7)

Answer 1

The coordinate of point E is (9, 3).

Step-by-step explanation:

To find the coordinate of point E, we can use the given length of DE and the coordinate of D. Since DE is 10 units long, we need to move 10 units from point D along the x-axis. Since D is located at (-1, 3), we add 10 to the x-coordinate of D to find the x-coordinate of E. Therefore, the coordinate of E is (9, 3).
