Answer:
The graph in the attached figure
Step-by-step explanation:
Let
y------> the total cost
x------> the number of shirts
we know that
The linear equation is
[tex]y=1.50x+4.50[/tex] ------> equation of the line
To graph the line find the intercepts
The y-intercept is the value of y when the value of x is equal to zero
The x-intercept is the value of x when the value of y is equal to zero
Find the y-intercept
For x=0
[tex]y=1.50(0)+4.50=4.50[/tex]
The y-intercept is the point (0,4.50)
Find the x-intercept
For y=0
[tex]0=1.50x+4.50[/tex]
[tex]1.50x=-4.50[/tex]
[tex]x=-4.50/1.50=-3[/tex]
The x-intercept is the point (-3,0)
Plot the intercepts to graph the line
see the attached figure
