Question

# Draw the graph of each of the following linear equations in two variables:$$y = 2x$$.

Solution

## $$y=2 x\cdots(1)$$To draw the graph ,we need at least two solutions of the equationPut $$x=0$$ in $$(1)$$$$y=2(0)=0$$So $$(0,0)$$ is a solution of the equationPut $$x=5$$ in $$(1)$$$$y=2(5)=10$$So $$(5,10)$$ is a solution of the equationWith these two solutions we can draw graph of $$y=2x$$Mathematics
