Explanation:

#21-3y=0" simplifies to"#

#-3y=-21rArry=(-21)/(-3)rArry=7#

#"This is a horizontal line parallel to the x-axis and"#
#"passing through all pints in the plane with a "#
#"y-coordinate of 7"#

#"plotting any set of points with "y=7#

#(-2,7),(0,7),(3,7)" then"#

#"Draw a straight line through them for graph of "y=7#
graph{(y-0.001x-7)=0 [-22.5, 22.5, -11.26, 11.24]}
