2. Find the distance between the points (-1, 3) and (5, 0)
3. Find the midpoint between the points (3, 1) and (1, 5)
4. Find the midpoint between the points (5, 2) and (-1, -2)
2.

Answer 2

@Jigglypuff123 please help me.

Answer 3

Please look for and type in (here) the formula for the distance between two given points in a plane when the coordinates of the points are given.

Answer 4

Use the distance formula!

Answer 5

Right. And please find the "midpoint formula." Once you have these formulas, the rest is easy. Have you a reference book? Are you good at looking up terms such as "distance formula" online?

Answer 6

KamiBug has generously provided the distance formula, exactly what you needed for the 1st 2 questions.

Answer 7

Graphing the points and the line segments between them also helps. Notice that the distance formula is just the Pythagorean Theorem (this distance to be found is the length of they hypotenuse), and finding a midpoint is the same as finding the average of two numbers.

Answer 8

Here's the midpoint formula for future reference, as well! =)

Answer 9

Kudos to Cliff and Kami for this helpful info!

Answer 10

Aqua: Mind asking some questions (if you need to) to get on course solving these problems?

Answer 11

\[d=\sqrt{\left( x2-x1 \right)^2+\left( y2-y1 \right)^2}\]

Answer 12

Surjithayer is reminding you of the same distance formula provided by KamiBug earlier. That's a strong hint that you, @AquaStone316 , ought to be trying to figure out how to insert into the distance formula the coordinates of the 2 points given in the first part of your posted question.

Answer 13

midpoint = ( (x2 + x)/2 , (y2 + y)/2 )
distance = sqrt( (x2 - x)^2 + (y2 - y)^2 )

Answer 14

@AquaStone316 : Any chance we'll be hearing from you soon? The more you're involved, the more you'll learn.

Answer 15

Thanks for the medal @AquaStone316 and @CliffSedge ! ^.^

Answer 16

I got it now, thanks.
