**Question:**rewrite equation as a function of x. not sure how to do it...

-3x+4y=11

**Answers:**

" rewrite equation as a function of x " means that they want you to write the function " in terms of x "...

-3x+4y=11

add "3x" to both sides of the equation... like this...

(-3x + 4y) + 3x = 11 + 3x

combine "like" terms... and you get...

4y = 11 + 3x

Now divide both sides by 4... like this...

4y / 4 = (11 + 3x)/4

the 4's on the left cancel each other out... leaving you with...

y = 11/4 + (3/4)x

OR

y = (3/4)x + 11/4

f(x) = (3/4)x + 11/4

Hope this helps!

-3x=-4y=+11

x= -4/3-11/3

I think

-3x + 4y=11

---------- ------

-4y -4y

-3x=11-4y

---- --------

-3 -3

x=11-4y

. ---------

. -3

It's been forever since I've done that, hope it's right!
