Solution

For this case we need to remember that the general equation for a line is given by:

y= mx+ b

Where m represent the slope and b the intercept

And we can find the slope with this formuala:


m=(y_2-y_1)/(x_2-x_1)

And we can use (50, 725) and (100,1325) and we have:


m=(1325-725)/(100-50)=12

And the intercept would be:

725 = 50*12 +b

b= 725 - 600

b= 125

and the equation would be given by:

y= 12 x + 125

And the y intercept represent the starting value of 125$ no matter the number of guests
