Answer: The graph is attached.
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:
Where "m" is the slope and "b" is the y-intercept.
We can find "b" substituting the slope and coordinates of the (4,3) into thte equation , and then solving for "b":
By definition, the line intersects the x-axis when "y" is zero.
Then, we need to substitute the y-intercept and 
into and then solve for "x" in order to find the x-intercept:
Knowing the x-intercept and the y-intercept, we can graph the line (The graph is attached)
