The formula is y = 70x, and for brand-new clients, it is y = 70x + 100.
The form of a linear equation is:
y = mx + b
where y and x are variables, m represents the line's slope, and b represents the y-intercept
Let y be the total payment and x denote the number of months of service.
a) A cable provider charges $70 monthly, thus
y = 70x
b) There is an extra one-time $100 service charge, so:
y = 70x + 100
Consequently, the equation is given by y = 70x, and for the additional clients, y = 70x + 100.
