Question

Find the distance between points P1(-1, 1) and P2(4, -4). Then find the coordinates of the midpoint of the segment that has endpoints at P1 and P2.

Answer 1

ok so d=sqrt(a^2+b^2), a=x2-x1,b=y2-y1

Answer 2

here we see x1=-1, x2=4,y1=1,y2=-4

Answer 3

sqrt 50

Answer 4

7.1

Answer 5

midpoint has formula((x1+x2)/2,(y1+y2)/2)

Answer 6

Do you input those numbers into that for the second answer?

Answer 7

yes

Answer 8

would it be (3/2, -3/2)? but it looks like they're asking for it in decimal form

Answer 9

well, 3/2 is 1.5 right?

Answer 10

yes so it would be 1.5, -1.5

Answer 11

so the entire answer would consist of 7.07; (1.5, -1.5)

Answer 12

great! you did it!

Answer 13

thank you!
