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

Explanation:

Substitute #y# for #g(x)#.

#y=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)#
#x=0#
#y=4#

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

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