What is the slope of the line 3 + 4x = 2y - 9
SSSSS [86.1K]
Hello! 

Ok so ideally we would like to see this in y=mx+b form. But it will take some algebreic skills to ninja our way through this. 

I'll show my steps so you can follow, 

3+4x = 2y - 9 (original equation) 

Next we just add 9 to both sides, 

12 + 4x = 2y, now we can divide both sides by 2,

y=2x+6 as our final equation. This is in y=mx+b form, thus the slope of our line is 2 because the 2 is sitting in the m space of the equation. If you  still dont understand linear stuff, I'd google slope-intercept form 

Hope this helped!
