Medal and Fan!!


The vertices of a right triangle are (–3, 5), (4, –1), and (4, y).

What is the value of y?

A.
–3

B.
–1

C.
4

D.
5

Answer 1

Have you graphed those three points yet?
Are you really better off by not following my advice regarding this problem?

Answer 2

This figure is a right triangle. How would you go about figuring out the value of y, after having graphed the triangle?

Answer 3

What do you think it is?

Answer 4

A or maybe B

Answer 5

mostly B though

Answer 6

No that would be the same as the second point

Answer 7

ohh, okay...

Answer 8

I graphed this triangle myself and saw the answer to this problem immediately.

Answer 9

Good job some dont know how to graph them though.

Answer 10

I can graph them, but I am finding this one confusing to graph the exact points...

Answer 11

Clue: this is a RIGHT triangle, which means that one angle, the one marked by (4,y), is 90 degrees. That fact, combined with the locations of points (–3, 5), (4, –1), is enough to enable you to figure out the value of y.

Have you used the Draw utility before? If not, why not give it a try? Plot (–3, 5) and (4, –1).
Draw a horizontal line through y=5.

Answer 12

and theres your answer in disguise

Answer 13

umm, okay.. thx

Answer 14

Please review my previous comments. finish graphing this triangle. Identify the y coordinate of the point at which you have a right angle.

Answer 15

yes, i got the answer.. thx!

Answer 16

You're welcome.
