Answer:
y=4/3-1/6x
Step-by-step explanation:
1) subtract "x" from both sides:
6y=8-x
2)divide by 6 on both sides(EVERYTHING WILL BE DIVIDED BY 6)
6y/6=(8-x)/6
y=(8-x)/6
2)simplify:
y=4/3-x/6
Answer:

Step-by-step explanation:
Given : The formula for the area of a trapezoid with altitude k and bases m and n is 
We have solve for m .
Consider the given formula 
Multiply both side by
, we have,

Now subtract n both side, we have,

Thus,

let's recall the vertical line test, if a vertical line hits the graph or points twice, then is NOT a function. Check the picture below.
This diagram shows how 2/7 = 8/28 by showing that you can color in more squares or duplicate that amount of squares 4 times in order to get 8/28. (Since 2/7 x 4/4 = 8/28.)
