Step-by-step explanation:
If you find where the line crosses the y-axis, and count to the next official and visible vertex, you will get 3 up or down, over 1 left or right. It's called rise over run. And as the line is drawn from the left to right side, it's a negative line.
20 - (4xn) = 4 is the equation
When you multiply or divide a whole number by a power of ten just add the zeros. 5 to the 100000 power is 500000. Five zeros. Hope this helps. Just a little trick and pattern I noticed which helps. :)
