# Math-- Ms. Sue??

You are designing a rectangular playground. ON YOUR SCALE DRAWING, THE VERTICES OF THE RECTANGLE ARE (6,3), (6,5), AND (8,3). wHAT ARE THE COORDINATES OF THE FOURTH VERTEX?

1: (4,5)
2: (8,5)
3: (8,1)

Determine which ordered pair is NOT a solution of y = -5x - 4

2: (7,-39)
3: (-7,31)
4: (8,-44)

find three solutions of the equation y =9x-4
1:(-5,-49), (-2,-22), (3,23) <- My Answer
2:(-5,-49), (2,-22), (3,23)
3:(-5,-49), (-2,22), (-3,23)
4:(5,-49), (-2,22), (-3,23)

Determine which pair of points has a positive slope.

1: (5,-4), (-2,1) <_ My Answer
2: (-10, -2), (6,6)
3: (6,-10, (2,10)
4: (5,-1, (-6,6)

1. #1 , wrong.
If you plot your points you will see that it is (8,5)
notice that now two pairs of points have the same x , making the lines vertical, and 2 pairs of points have the same y, making the horizontal.

#2, ok
#3, ok

(5,-4) and (-2,1) -- slope = (1-(-4))/(-2-5) = 5/-7
my points:
(-10, -2) and ( (6,6)
slope = (6-(-2))/(6-(-10))
= 8/16 = +1/2
