Get Y by itself, so move X
Equation should look like 1/5y= x-6
Multiply by 1/5
Y = 5x-30
7% ordered coffee in 2008
In 2009 it increased by 43%
New % = original% x ( 1 + increased %)
New % = 0.07 x (1 + 0.43)
New % = 0.07 x 1.43
New % = 10.01 % ( round as needed)
Explaination:
The question is basically saying that a point on a graph has either a positive x and positive y, or a negative x and negative y. So where on a graph is the x and y both positive, and where on the graph is x and y both negative? I recommend you look it over before scrolling down.
(Spoiler Alert) The Answer:
Quadrant 1 is where x and y are both positive. This is the top right corner. Quadrant 3 is where x and y are both negative. This is the bottom left corner.
You wanna pick the one with the top right and bottom left corner.
I solve this answer by multiplying my decimals so I can see which on is the greatest, the least, and equal too.
