-7x+y=9 in Slope Intercept Form

Question

I need to help turning -7x+y=9 into slope intercept form.

Answer 1

Noah this is a very common problem

 

the first this thing to understand is what is he slope intercept form.  The basic understanding of the slope intercept form is 

 

y=mx +b  

 

y-result of function 

m- is the slope

b- is the y intercept

x- variable

 

In some cases you wont start in the slope intercept form in which case you can follow the steps below

 

10x -4+ y= 1

 

10x -4 +y=1

      +4    +4.    a). Move the constant to the  opposite  side of the equal sign.

 

10x+ y= 5

-10x       -10x    b). Move the x term to the opposite of side the equal sign.

 

y= -10x + 5 is the Final answer.

 

in summary Noah the goal is to get the y term on one side of the equal sign and all other terms on the opposite side of the equal sign. I hope this example will help you with your question.

 

 

 

 

 

 

Answer 2

It's a short walk, Noah! Just move that pesky -7x to the other side and you are done! That is the rule for all such questions: it isn't "slope-intercept form" until Y is alone.
