Y-2x=4
(+2x) (+2x)
Y= 2x+4
4 is in the B slot of Y=mX+B
it is therefore the Y intercept/

For the y intercept let x = 0 getting y = 4

At the y-intercept, x is equal to 0. So, replace every x with "0".
y-2(0)=4
y=4

what you first need to do is transfer this equation into y=mx+b form. to this you need to add 2x to both sides
2x+y-2x=4+2x-------->y=2x+4
In such an equation, the y-intercept is the "b" in the equation.
Therefore, the y intercept is 4

Here are two ways to find this:
Option #1:
y-2(0)=4
y=4
Option #2:
Add 2x from both sides:
y=2x+4
y=2(0)+4
y=4
I hope this helps!

y-2x=4
-2x
y=-2x+4
Therefore you put x as 0
2(0)+4=4
Therefore y=4

y - 2x = 4
y - 2x + 2x = 2x + 4
y = 2x + 4
The y intercept is 4
