Answer:
see the procedure
Step-by-step explanation:
we have
[tex]f(x)=-3x+7[/tex]
This is the equation of a line in slope intercept form
where
[tex]m=-3[/tex] ----> the slope
[tex]b=7[/tex] ----> the y-coordinate of y-intercept
To graph the line find out the intercepts
The y-intercept is the point (0,7) ----> given value
The x-intercept is the point (2.33,0) ---> Remember that the x-intercept is the value of x when the value of the function is equal to zero
with the points (0,7) and (2.33,0) sketch the graph
using a graphing tool
Plot the points and join to graph the line
see the attached figure
The domain is all real numbers
The range is all real numbers
