The graph of given pair of equations is plotted below:

Step by step solution

Step 1. Given information

A pair of equations $y = 5 x$ and $y = 5$ is given.

Step 2. Find three points that are solutions to the equation y=5x.

First take $x = 0$ and solve for $y$ as shown below:

$y = 5 (0) y = 0$

Next take $x = 2$ and solve for $y$ as:

$y = 5 (2) y = 10$

At last take $x = 1$ and solve for $y$ as:

$y = 5 (1) y = 5$

Thus, we get ordered pairs as $(0, 0), (1, 5), (2, 10)$ .

Step 3. Find three points that are solutions to the equation y=5.

The equation $y = 5$ is a horizontal line of the form $y = b$ passing through the y-axis at $(0, b)$ . The equation $y = 5$ has only one variable $y$ and the value of $y$ is constant.

The graph is a horizontal line passing through y-axis at $5$ .

Step 4. Create a table of ordered pairs for both equations.

The tables are created using ordered pairs as shown below:

Table for $y = 5$ is as:

$x$	$y$	$(x, y)$
1	5	(1,5)
-5	5	(-5,5)
10	5	(10,5)

Table for $y = 5 x$ is as:

$x$	$y$	$(x, y)$
2	10	(2,10)
0	0	(0,0)
1	5	(1,5)

Step 5. Graph both equations.

Both equations are plotted on same rectangular coordinate system by plotting the points from the tables and drawing the lines joining the points in the graph as shown below:
