How do you graph the line # f(x)=9#?

Answer 1

#"see explanation"#

#"the equation" f(x)=9#

#"is a line parallel to the x-axis passing through all points in"# #"the plane with a y-coordinate of 9"#

#"choosing 2/3 points with a y-coordinate of 9 and drawing"# #"a straight line through them will give the graph"# graph{y-0.001x-9=0 [-40, 40, -20, 20]}
