For y=4 draw a horizontal line through the y-axis at point (0,4). Y-axis is the vertical.
For x=-3 draw a vertical line through the x-axis at point (-3,0). X-axis is the horizontal.
If we are going to analyze the problem very well, the equation that we will be able to make would be: 2x + 6y = 72
72 is the oz of water conditioner to use in his fish tanks.
small tanks would require 2 oz of conditioner
large tanks would require 6 oz of conditioner
There is only one point which satisfy's the above equation.That is the points of (0, 12) and (36, 0)
1.4
To make a percent a decimal, divide it by 100.
140 ÷ 100
= 1.4
