What is the slope of a line that passes through (-2,-3) and (1, 1)
Paul [167]
The slope of (-2, 3) & (1, 1) is ( 4, 2). The reason why the answer is (4, 2) is that if you look at a number line from left to right you'd see that -2 takes four steps to get to positive 2.

                     -10 -9 -8 -7 -6 -5 -4 -3 -2 -1  0  1 2 3 4 5 6 7 8 9 10
                                                           ↑  ↑  ↑  ↑ ↑
                                                                1  2  3 4

As for the other plot, you have to think: How many times does 1 need to jump to get to 3?

                     -10 -9 -8 -7 -6 -5 -4 -3 -2 -1  0  1 2 3 4 5 6 7 8 9 10
                                                                       ↑ ↑ ↑
                                                                          1  2 
This is important to remember, the numbers to your right is your y  and the numbers to your left is your x. 

(-2, 3) (1, 1)
       
↑      ↑
        y     y

(-2, 3) (1, 1)
  ↑       ↑
  
x       x

I hope I helped :)

Answer:

  • y = 55x
  • y = 46x +45

Step-by-step explanation:

A. The regular cost is 55 per person. Using the given variable definitions, that cost can be expressed as ...

  y = 55x

__

B. The party special cost is 46 per person, with an added fee of 45. That cost can be expressed as ...

  y = 46x +45

_____

As you know, the cost of a purchase is the product of the cost of an item and the number of items. Here, the cost of entry is the cost of the item of interest, and the number of persons needing entry is the number of items. The party special has the addition item of a private room, so its cost is added to the total for the party special.
