Answer:
Step-by-step explanation:
<em>(1).</em> x + y = 9 and y = - 7x <em>( Neither )</em> ; lines intersect.
<em>(2).</em> y = 3x - 3; 12x - 4y = 12 <em>( Neither ) </em>; Lines are overlapped or both equation are of the same line.
<em>(3).</em> 7y = 2x + 1; 14x + 4y = 12 <em>( Perpendicular )</em> ; =
and
= -
, slopes are opposite reciprocals.
<em>(4).</em> x - 4y = 18; y = x + 4 <em>( Neither )</em> ; lines intersect.
<em>(5).</em> 3x - 4y = - 1; 3y = - 4x + 5 <em>( Perpendicular )</em> ; =
and
= -
, slopes are opposite reciprocals.
