Answer:
Perimeter =28 units.
Area = 45 unit^2.
Step-by-step explanation:
The length of first side (joining first 2 points) = 5 - (-4) = 9 (as y coordinates are both -5)
The line joining the 2nd and third points = 0 - (-5) = 5
The line joining the 3rd and 4th points = 5 - (-4) = 9.
The line joining the first and 4th points = 0 - (-5) = 5
So the perimeter = 2(5) + 2(9)
= 28 units.
Area = 5*9 = 45 unit^2.
Answer:
2x-5=4
2x=9
x=9/2=4.5
or
2x-5=-4
2x=1
x=1/2
Step-by-step explanation:
The library is in the 4th quadrant (+x,-y)
So the English class must have a positive x and a negative y
(4,-5) is the only point that fits
Answer:
-1/3
Step-by-step explanation:
y-y/x-x
=
(1- - 1)/(-3-3)= 2/-6 = -1/3
