Question

x+y=0 ; 2x-y=9
solve simultaneously equation is graphically
and table also
on graph

Answer 1

hey guys
ur answer is below

Let the system of pair of linear equations be
a1x + b1y = c1 ….(1)
a2x + b2y = c2 ….(2)
We know that given two lines in a plane, only one of the following three possibilities can happen –
(i) The two lines will intersect at one point.
(ii) The two lines will not intersect, however far they are extended, i.e., they are parallel.
(iii) The two lines are coincident lines.

Answer 2

x + y = 0
x = -y

x 1 2 3
y -1 -2 -3

2x - y = 9
-y = 9 - 2x
y = -9 + 2x

x 2 3 4
y -5 -3 -1

These are the points.
If you mark my answer as the brainliest, then i will edit the answer and give u the graph also.
