If the lines are parallel (have the same slope but different intercepts) . . .
no solution, because they never cross.
If the lines have different slopes . . .
one solution, because they have exactly one common point.
If the lines have the same slope and the same intercept . . .
infinitely many solutions, because every point on one line is also a point on
the other line, one lays right on top of the other, and when you look at them on
the graph, it looks like only one line.

Step-by-step explanation:
Answer: Nazim have to pay $35 for 20 slices of pizza.
Monthly cost for x slices = 5+1.5x
Step-by-step explanation:
Let x = number of slices
As per given,
Total monthly cost for x slices = (membership cost) +(discounted price) ×(x)
i.e. Total monthly cost for x slices = 5+1.5x
If x=20
Then, Nazim have to pay = 5+1.5(20)
= 5+30= $35
i..e Nazim have to pay $35 for 20 slices of pizza.
Monthly cost for x slices = 5+1.5x
