Question 1
Graphically, the pair of equations
6x – 3y + 10 = 0
x – y + 9 = 0
Represents two lines which are
(A) intersecting at exactly one point.
(B) intersecting at exactly two points.
(C) coincident.
(D) parallel.
The first equation is
6x–3y+10=0
⇒2x−y+103=0
y=2x+103
x0−53y1030PointsABAnd table for 2x−y+9=0x0−92Y=2x+990PointsCD
Hence, the pair of equations represents two parallel lines
