A. What iS the slope of the line that passes through (-2, 3) and (4, -5)?
Thepotemich [5.8K]

Answer:

slope = - \frac{4}{3}

Step-by-step explanation:

Calculate the slope m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (- 2, 3 ) and (x₂, y₂ ) = (4, - 5 )

m = \frac{-5-3}{4-(-2)} = \frac{-8}{4+2} = \frac{-8}{6} = - \frac{4}{3}

You and your friends go to the movies. The cost of admission is $9.50 per person create a table . Can anyone help me create the
KiRa [710]

Answer:

To create a table like that, you can have two columns. One labeled "Number of People" and the other "Price in Dollars." Since each ticket costs $9.50, the cost for one person must also be $9.50. For two people it would be $19.00 (9.50×2), and so on. The cost of the tickets are proportional to the amount of people. This is because the tickets sell at a constant rate, also know as the constant of proportionality, which in this case is 9.50.

Step-by-step explanation:

<u>Number of people </u>                                         <u>Price In dollars</u>

             1                                                                  9.50

             2                                                                 19.00

             3                                                                28.50

So on.....

I hope this helps you :)
