Write each of the equations in slope intercept form

Oct 26th, 2015

There are no equations in your question However, I can tell you how to write equations in slope-intercept form.

y=mx+b is always the form.

So if you have an equation that is not specifically solved for y then it is not in the correct form.

Here is an example.

-6x+3y=18

Add 6x to both sides of the equation so that the y term is alone on the left side of the equation.

6x-6x+3y=6x+18

3y=6x+18 The x terms have cancelled one another. Now divide by 3 on both sides of the equation to get y isolated.

3y/3=6x/3+18/3

y=2x+6

Now the equation is in slope intercept form because y is isolated and looks like y=mx+b the proper form.

An equation is 5x+2y=-10

5x+2y=-10 Subratct 5x from both sides of the equation. This is to move 5x to the right side.

-5x+5x+2y=-5x-10

2y=-5x-10 because the x terms on the left side cancel one another.

Now divide both sides by 2 to get y isolated (aka alone)

2y/2=-5x/2-10/2

y=-5x/2 - 5

The -5/2 does not reduce that is why it stays in the same fraction form.
