Write each of the equations in slope intercept form

Oct 26th, 2015

Thank you for the opportunity to help you with your question!

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.


Please let me know if you need any clarification. I'm always happy to answer your questions.

An equation is 5x+2y=-10

Oct 26th, 2015

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.
