Step-by-step explanation:
When you are shrinking or enlarging your shape, be sure to compare the same things in the same order. Here we just kept putting the original length of the side on top and the new length of the side on the bottom. 2/7 is what they said to make the enlargement. The original length if the longest side was 14. So the 14 goes on top where we were putting the original lengths and x (bc we dont know it yet) is the new length that goes on the bottom of the fraction (it's a ratio, written like a fraction, so we can do mathy work on it).

Step-by-step explanation:
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.
