Answer:
The graph in the attached figure
Step-by-step explanation:
we have
This is the equation of a line in slope intercept form
we know that
To graph a line we need tow points
<em>Find the intercepts</em>
<u><em>Find the y-intercept</em></u>
The y-intercept is the value of the function when the value of x is equal to zero
For x=0
The y-intercept is the point (0,-3)
<u><em>Find the x-intercept</em></u>
The x-intercept is the value of x when the function is equal to zero
For f(x)=0
The x-intercept is the point (6,0)
Plot the intercepts and joint the points to graph the line
The graph in the attached figure
