\

The equations of linear system are $\"\"$ .

\

For ease of graphing, write each equation in slope - intercept form.

\

Rewrite equation 1: $\"\"$ in slope - intercept form.

\

Subtract 7x from each side.

\

$\"\"$

\

$\"\"$

\

$\"\"$ .

\

Divide each side by 5.

\

$\"\"$

\

$\"\"$ . $\"\"$

\

Rewrite equation 2: $\"\"$ in slope - intercept form.

\

Add 9x to each side.

\

$\"\"$

\

$\"\"$

\

$\"\"$ . $\"\"$

\

The equations $\"\"$ of graph in the same coordinate plane is

\

$\"graph$

\

Observe the graph, the lines appear to intersect at the point $\"\"$ . $\"\"$

\

To check the ordered pair $\"\"$ is a solution of linear system, substitute 1 for x and $\"\"$ for y in each of the original equations.

\

Substitute 1 for x and $\"\"$ for y in the equation 1: $\"\"$ .

\

$\"\"$

\

$\"\"$

\

$\"\"$ .

\

The above statement is true, so $\"\"$ is a solution of equation 1. $\"\"$

\

Substitute 1 for x and $\"\"$ for y in the equation 2: $\"\"$ .

\

$\"\"$

\

$\"\"$

\

$\"\"$ .

\

The above statement is true, so $\"\"$ is a solution of equation 2.

\

Because $\"\"$ is a solution of each equation, it is a solution of the linear system. $\"\"$

\

The solution of the linear system is $\"\"$ .
