I find it convenient to let a graphing calculator draw the graph (attached).

If you're drawing the graph by hand, there are a couple of strategies that can be useful.
The first equation is almost in slope-intercept form. Dividing it by 2 will put it in that form:
y = 2x -4
This tells you that the y-intercept, (0, -4) is a point on the graph, as is the point that is up 2 and right 1 from there: (1, -2). A line through those points completes the graph.
__
The second equation is in standard form, so the x- and y-intercepts are easily found. One way to do that is to divide by the constant on the right to get ...
x/2 +y/3 = 1
The denominators of the x-term and the y-term are the x-intercept and the y-intercept, respectively. If that is too mind-bending, you can simply set x=0 to find the y-intercept:
0 +2y = 6
y = 6/2 = 3
and set y=0 to find the x-intercept
3x +0 = 6
x = 6/3 = 2
Plot the intercepts and draw the line through them for the graph of this equation.

Here, we have suggested graphing strategies that don't involve a lot of manipulation of the equations. The idea is to get there as quickly as possible with a minimum of mistakes.
Answer:
Carmen had the largest red to green apple ratio of 5 : 3
Step-by-step explanation:
Red apples : Green apples
Carmen = 20 red apples : 12 green apples
= 20 / 12
= 5 / 3 = 1.67
= 5 : 3
Dylan = 12 red apples : 10 green apples
= 12 / 10
= 6 / 5 = 1.2
= 6 : 5
Eli = 16 red apples : 20 green apples
= 16 / 20
= 4 / 5 = 0.8
= 4 : 5
Carmen had the largest red to green apple ratio of 5 : 3
