Question

Draw the graph of the equation $y=3x$

Answer 1

Given equation is $y=3x$

When $x=1,\Rightarrow y=3\times 1=3$

When $x=2,\Rightarrow y=3\times 2=6$

When $x=3,\Rightarrow y=3\times 3=9$

$x$	$1$	$2$	$3$
$y$	$3$	$6$	$9$

Plot the points $A(1,3),B(2,6),C(3,9)$ on the graph paper.Join these points by a straight line $AC$
