Answer:

Explanation:
We have been given a system of equations. We are asked to solve the given system by graphing.

We can see both equations are in slope-intercept form of equation.
The line of equation
will cross the y-axis at (0,9) and will have a slope of
.
The line of equation
will cross the y-axis at
and will have a slope of
.
Please find the attachment for the graph of both equations.
We can see that both lines intersect at point
, therefore, the solution of our give system is
.
