rewrite each equation in standard form.
Note: Standard form for a line is ax+by = c
-----
1. y=x+9
x-y = -9
--------------
2. y=3x+7
3x-y = -7
--------------
3.y=4x+8
4x-y=-8
===============

Hi

standard form of a line is in the form Ax + By = C , where a is positive.

Performing the operations necessary to have this format:

1. y = x+9     |subtracting  y and 9 from both sides of the equation

   -9 = x - y   |in the form Ax + By = C

OR   x - y = -9

2. y = 3x + 7   |subtracting  y and 7 from both sides of the equation

   -7 = 3x - y

OR     3x - y = -7  |in the form Ax + By = C

3. y  = 4x + 8 |subtracting  y and 8 from both sides of the equation

   -8 = 4x - y

OR      4x - y = -8  |in the form Ax + By = C
