How do you graph the equation y equals x plus 4?

Answer 1

y = x + 4

Solve for the y intercept (when x = 0)

y = (0) + 4

y = 4

So we have one coordinate: (0,4)

Now solve another point, let's make y 0:

0 = x + 4

x = -4

So we have a second coordinate: (-4, 0)

Plot those two points on the graph, and draw a line connecting them. The line additionally is keeps going past those points on both sides, unless it is bounded by a restriction -- in this case it is not.
