Melissa per page rate is $75 while her start up fee is $35.
A linear equation is given by:
y = mx + b
where y, x are variables, m is the rate of change, b is the initial vale of y (y intercept).
Let y represent the total cost for designing x pages.
Taking the points (2, 185) and (8, 635).
The equation is given as:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-185=\frac{635-185}{8-2} (x-2)\\\\y-185=75x - 150\\\\y=75x+35[/tex]
Hence Melissa per page rate is $75 while her start up fee is $35.
