Question

Rectangle ABCD has the coordinates shown.
A (2,1)
B (1,3)
C (5,5)


Find the coordinates of point D.
A). (5,3)
B). (6,2)
C). (6,3)
D). (7,2)

Answer 1

the same idea will be used as last time

1) plot all 3 points

2) find the slope from B to C

3) start at A and follow the same slope to get to D

Answer 2

this works because a rectangle is a parallelogram

Answer 3

okay, I thought so. let me do the work and I'll come back to ya.

Answer 4

for my slope I got 1/2 is that right?

Answer 5

good

Answer 6

but in this case, it helps to not reduce the fraction

Answer 7

so keep it at 2/4

Answer 8

0.5

Answer 9

now start at A, go up 2, then over to the right 4

Answer 10

I got B. (6,2)

Answer 11

close

Answer 12

no no no , 6,3?

Answer 13

better
