Question

what are the coordinates for the midpoint of line YZ.

Answer 1

add x coordinates then divide by 2
.. y ...................................
and you'll have your midpoint

Answer 2

Midpoint Line XY Coordinates

\[(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})\]

Answer 3

so is it (2,-1.5)

Answer 4

Perfect, good job

Answer 5

thanx

Answer 6

now what about the length of DF ? D (-4, 1) E (3,4) F (3,0)

Answer 7

\[Length=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\]

Answer 8

i cant find the answer

Answer 9

What are your coordinates for point D and F?

Answer 10

D (-4,1) F (3,0)

Answer 11

Okay let y2=0, y1=1, x2=3 and x1=-4. When you sub these values into the equation I wrote above, what do you get?

Answer 12

7

Answer 13

so is it
