Answer 1

16) The graph y= 5 is a line parallel to ${\underline{y-axis}}$ axis.

17) The pair of equations y = 0 and y = -7 has no solution.

EXPLANATION:-

We know that equation of the form y=a is a line parallel to x-axis at distance 'a'from it . y=0 is the equation of the x-axis and y=−7 is the equation of line parallel to the x-axis so, these two equations two parallel lines . therefore, there is no solution.

18) The number of solutions a pair of coincident lines have no solution.
