Question

Can anyone please help me. Points P(1, 5) and Q(4, 1) on a coordinate grid represent side PQ of triangle PQR. What is the length of side PQ of the triangle?

5 units
25 units
7 units
13 units

Answer 1

Would the answer be 7 units?

Answer 2

length of PQ : Distance formula : \[\sqrt{(x2-x1)^2 + (y2-y1)^2}\]
\[\sqrt{(4-1)^2 +( 1-5)^2}\]
\[\sqrt{25}\] \[= 25\]

Answer 3

= 5 *

Answer 4

Oh ok, thank you I see where I messed up. Thank you so much for explaining it.

Answer 5

yep i bet you mess up with the distance formula... anyway hope i was helpful good luck

Answer 6

You were very helpful thanks again.
