Question

$2x + y = 0 \\ 4x - 3y = 5$
Solve using Elimination Method​

Answer 1

Step-by-step explanation:

We can see that the equation represents a straight line. Also that

Two points are sufficient to draw a straight line.

However, it is advisable to have three points so that error, if any, while calculating two points on the lines can be cross checked.

For

x

=

0

, we obtain

y

=

0

, so origin is a point on the line.

For

x

=

5

, we obtain

y

=

−

10

, so next point is

(

5

,

−

10

)

For

x

=

−

5

, we obtain

y

=

10

, another point is

(

−

5

,

10

)

Plotting these points we get the graph

graph{2x+y=0 [-20, 20, -10, 10]}
