Use the equation y=x+4y=x+4 to find two points. Plot them, then draw a straight line through them.

Explanation:

Substitute yy for g(x)g(x).

y=x+4y=x+4 is the point-slope form for a linear equation.

Use the equation to find two points on the line. Plot the points and draw a straight line through them.

Point A: (0,4)(0,4)
x=0x=0
y=4y=4

Point B: (-4,0)(4,0)
y=0y=0
x=-4x=4

graph{y=x+4 [-9.96, 10.04, -3, 7]}
