how do you find distance of two points on a coordinate plane

IMURDADDY4EVER:

Do you know what a coordinate plane is?

IMURDADDY4EVER:

Do you know what the Pythagorean Theorem is?

nalaynana:

well i found something from Google Derived from the Pythagorean Theorem, the distance formula is used to find the distance between two points in the plane. The Pythagorean Theorem, a2+b2=c2 a 2 + b 2 = c 2 , is based on a right triangle where a and b are the lengths of the legs adjacent to the right angle, and c is the length of the hypotenuse.

i told you, the distance formula is \[d=\sqrt{(x2-x1)^2}+(y2-y1)^2\] just plug in the x and y values from your ordered pair.

IMURDADDY4EVER:

Your going to find endpoints (x1,y1) and (x2,y2) using the formula \[d = √ ( x 2 − x 1 ) 2 + ( y 2 − y 1 ) 2\]

I didnt see she put that there. ALso, I was helping them but people like to take over but ian trippin doe

mxddi3:

Well, i don't know your ordered pairs so i cant say. also, i wasnt taking over, i was helping them on their last post and then they made this one. And keep comments related to the post please (:

mxddi3:

Can you tell me the ordered pairs that you have, please?

carlosesgirl:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @mxddi3 Can you tell me the ordered pairs that you have, please? \(\color{#0cbb34}{\text{End of Quote}}\) 49,36 for 7,6 and then I got -9,4

mxddi3:

is it the same ordered pairs from last time. i dont remember the first one, it was like (3,2) i think and (7,6). These ones?

carlosesgirl:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @mxddi3 is it the same ordered pairs from last time. i dont remember the first one, it was like (3,2) i think and (7,6). These ones? \(\color{#0cbb34}{\text{End of Quote}}\) yes and when I squared then I got those answers

mxddi3:

ok so first you have to do x2-x1 and THEN square it, so for the x, (7- (-3))^2 did you do that ?

carlosesgirl:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @mxddi3 ok so first you have to do x2-x1 and THEN square it, so for the x, (7- (-3))^2 did you do that ? \(\color{#0cbb34}{\text{End of Quote}}\) no I did it the other way I did the two numbers together

mxddi3:

no, you have to follow the steps as they are written, please use the distance formula that has been provided and then plug the x and y values into the formula (they will come from your ordered pairs)

mxddi3:

the distance formula is \[d=\sqrt{(x2-x1)^2}+(y2-y1)^2\] so you have (-3,2) and (7,6) so write it out as \[d=\sqrt{(7-(-3)^2}+(6-2)^2\] NOW simplify.
