x+y-4=0

The slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.

y=mx+b

Move all terms not containing y to the right side of the equation.

Subtract x from both sides of the equation.

y-4=-x

Add 4 to both sides of the equation.

y=-x+4

y=-x+4

y=-x+4

Using the slope-intercept form, the y-intercept is 4.

b=4
