Opposite sides being parallel proves that hte figure is a parallelogram. The sides only appear to be equal so his conclusion is not valid. He would need to show that 2 adjacent sides of the parallelogram are equal ( using the distance formula) to prove that it is a rhombus.
Y = 3x - 2
-3x + y = -2
-3x = -y - 2
x = (1/3)y + 2/3

To find how many minutes of talk time is available per dolla, you have to divide 160 (number of minutes) by 40 (cost)
160/40 = 4
Therefore, it's 4 minutes per dollar
ANSWER:
y = 2/3x + 2
EXPLANATION:
Write the equation in slope intercept form
y=mx+b
-2x+3y=2
3y=2+2x
y=2/3x+2/3
From the slope intercept form, we know that the slope is m=2/3
To find an equation that is parallel, the slopes must be equal. Find the parallel line using the point-slope formula.
Substitute the slope 2/3 and the point (3,4) in the point slope form: y-y1=m(x-x1) which we get from m=y2-y1/x2-x1
y - (4) = 2/3 • (x-(3))
Simplify it
y - 4 = 2/3 • (x-3)
Solve for y
y - 4 = 2x/3 - 2
y = 2x/3 - 2 + 4
y = 2/3x + 2
