So basically how do i turn this 2x -Y - 4 = 0 equation into its slope intercept form
Thank you!
Thank you!

slope intercept form is: y=mx+b with m being the slope and b being the y-intercept.
Your equation is this:
2X-Y-4=0
First move everything away from the Y:
When something moves to the other side, its sign MUST CHANGE:
-Y=0-2X+4
See? I changed the sign of the 2x from positive to negative; I changed the sign of the 4 from negative to positive.
Now, on the right side, we can erase the 0. The 0 is only written if its the only thing on one side, by itself. Otherwise it's not written:
-Y=-2X+4
Now, we have -Y on the left side. We are looking for Y on the left side. To get Y on the left side, we must divide the other side by -1 because -Y is the same as -1Y:
Y=(-2x+4)/-1
Y=2X-4
So, your equation in slope intercept form is:
Y=2X+4
That's with a positive slope of 2 and Y=4 y-intercept.

You just need to rewrite the equation
I would just move y to the other side
2x - 4 = y
Now just reverse the equation so it looks better
y = 2x -4
You're done!!
