Test them
(x,y)
(2,4) and (3,3)
see if get true
(2,4)
-3(2)+5(4)=2(2)+3(4)
-6+20=4+12
14=16
false
(3,3)
-3(3)+5(3)=2(3)+3(3)
-9+15=6+9
6=15
false
neither
Answer: Point C
You can see on the graph that it’s -3 (3 to the left of 0) and it’s -2 (2 below the x axis)
C because 1/2 of brothers book plus 5 equals 7
The volume is 675 because when you multiply 20x15 you get 300 and when you multiply 25x15 you get 375. When you add 375+300 you get 675 as your volume.
OK so for this it will be simple
1,000 divided by 200 is 5
so if the plane took 5 hours to do 1,000 miles then the plane was traveling at option A. 200 miles per hour.
