Graph of the equation $y = 2 x$ :

Step by step solution

Given information:

The given equation is $y = 2 x$ .

Construct a table which contains the coordinates that are the solutions to the equation :

The given equation, $y = 2 x$ has both x and y. The y coordinates will change with respect to the x-values, since y values is dependent on the values of x.

$x$	$y = 2 x$	$(x, y)$
$- 2$	$y = 2 \times (- 2) = - 4$	$(- 2, - 4)$
$- 1$	$y = 2 \times (- 1) = - 2$	$(- 1, - 2)$
$0$	$y = 2 \times 0 = 0$	$(0, 0)$
$1$	$y = 2 \times 1 = 2$	$(1, 2)$
$2$	$y = 2 \times 2 = 4$	$(2, 4)$

Plot the graph :

Using the table given in the step 2, point the coordinates on the graph. Then join the points with the straight line.

we get the graph of the equation $y = 2 x$
