Phone plan. the monthly cost c of marge's phone plan is given by c=40 + m, where m is the number of extra minutes she uses in that month. name the slope and y-intercept in this situation, and explain what each represents

This equation takes the form y=mx+c.
however many minutes she uses, the base rate is 40.
y=mx+40.
c, 40 is the y intercept as it is when the number of miutes is 0.
there is no constant for m so we say it is 1. for every 1 minute used, the price goes up 1.

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
