Since there is a flat membership fee of $18, the y intercept is 18. And since there is a $3 fee per number of video games rented, n, the slope or rate of change of the linear equation is 3. The slope-intercept form of a line is:
f(x)=mx+b, where m=slope and b=y-intercept so in terms of n, games rented, the cost, f(n) is:
f(n)=3n+18
Step-by-step explanation:

Okay, so let's make a sample space where in one section, one toy is the leader of each group for as many possibilities as there are.
T K E
T E K
K E T
K T E
E T K
E K T
There are 6 possibilities, and so each arrangement has a 1 over 6 chance of being used.
B is 3, m is 0.75 x is number of miles
