ok im doing a math assignment and we have to make up a linear equation (one not in slope-intercept form), then change it into slope intercept and then graph the slope-intercept form. i know how to graph it and all but i cant change it into slope-int. i already made up a linear equation 6x-2y=8...can anyone change it into slope int? you can make up another equation and use that if this is too hard or something lol. k thanks...and this is 9th grade math so nothing too big lol.

Okay, I'll make up another equation, and you can use it to help you figure out your homework.
Let's say 16x + 4y = 12
slope intercept form is y = mx + b, where m is the slope and b is the y-intercept.
So, firstly, you need to move the x to the other side of the equation:
4y = -16x + 12
However, in slope-intercept form, the y cannot have a coefficient, so you need to divide out the 4:
y = -4x + 3
And there you go, in slope-intercept form!

just get y by itself.
6x-2y=8 Original
6x=8+2y Added 2y
6x-8=2y Substracted 8
3x-4=y divided everything by 2
y=3x-4 is your answer! Good luck!

Solve for y. Subtract 6x from both sides so you have -2x=-6x=8
Then divide both sides by -2, so you have y=(-6x+8)/-2, or
y=3x-4
