Find the intercept y equals x plus 4?

Answer 1

y=x+4 is the equation of a line in slope intercept form. This tells us 4 is the y intercept.
The point (0,4) is actually the point where the line intersects the y axis. To find where it intersects the x axis just let y=0. The means x=-4 is the x intercept. So the point (-4,0)
