Explanation:
21−3y=0 simplifies to
−3y=−21⇒y=−21−3⇒y=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]}
