choli [55]

Answer:

  In order down the left side, ...

  • y = 1/3x +2
  • y = 1/2x +3
  • y = 2x +6
  • y = -2x +3

Step-by-step explanation:

To put a linear equation in slope-intercept form, you solve for y, then simplify.

<u>x -3y = -6</u>

Subtract x and divide by -3:

  y = 1/3x +2

__

<u>2y -6 = x</u>

Add 6 and divide by 2:

  y = 1/2x +3

__

<u>-x +(1/2)y = 3</u>

Add x and multiply by 2:

  y = 2x +6

__

<u>2x +y = 3</u>

Subtract 2x:

  y = -2x +3

<em>Comment on the algebra</em>

Note that when we say add, subtract, multiply, or divide by something or other, we mean to <em>do that to both sides of the equation</em>. That is required by the properties of equality.

If you remember the rule: do the same thing to both sides of the equation, then algebra suddenly becomes much easier.
