Question

16. The pair of equations x= a and y = b graphically represents lines which are
(a) parallel
(b) intersecting at (b, a)
(c) coincident
(d) intersecting at (a, b)​

Answer 1

Answer:

Step-by-step explanation:

The equations are  

$x=a$

and  

$y=b.$

The graph of  

$x=a$

is a line parallel to  

y

-axis and  

$y=b$

is a line parallel to  

x

-axis.

∴

the angle between them is  

90

o

, i.e. they intersect.

So, the equations are consistent.

Now solving simultaneously, the solution is  

$(a,b).$

So, the point of intersection is  

$(a,b).$

Hence, option D is correct
