Okay I sent in the previous lesson and I'm awaiting for the teacher's response.

Meanwhile I figured out the first 10 from the next lesson but need help with the second 10. The lesson is "The Cartesian Coordinate System and the Distance Formula" I'll wait for you to wake up and reply. Thanks again for the previous lesson!

Find the distance between the two points:

11. (-20, -4) and (-7, -6)

A 4

B SQRT(61)

C SQRT(290)

D 5

E SQRT(173)

F SQRT(180)

12. (1, 1) and (-4, 1)

A 4

B SQRT(61)

C SQRT(290)

D 5

E SQRT(173)

F SQRT(180)

13. (-3, 22) and (-14, 35)

A 4

B SQRT(61)

C SQRT(290)
