Question

draw a graph: linear equations in two variables y=2x
​

Answer 1

Answer:

y=2x⋯(1)

To draw the graph ,we need at least two solutions of the equation

Put x=0 in (1)

y=2(0)=0

So (0,0) is a solution of the equation

Put x=5 in (1)

y=2(5)=10

So (5,10) is a solution of the equation

With these two solutions we can draw graph of y=2x
