Answer:

The slope is 2

Step-by-step explanation:

Given

(x_1,y_1) = (2,9)

(x_2,y_2) = (-1,3)

Required

The slope (m)

This is calculated as:

m = \frac{y_2 - y_1}{x_2 - x_1}

m = \frac{3 - 9}{-1 - 2}

m = \frac{- 6}{-3}

m =2

six friends are going to buy a pizza. Their chices are to biu 2 medium 10-inch diameter pizzas for 7:00 each, or 1 large 14 inch
11111nata11111 [884]
For this question, we want to find out the greatest amount of area of pizza for the least amount of money:

So we have two pizzas with a 10 in. diameter. Let us take one of those pizzas.

The formula for area of a circle is \pi r ^2; So the area for one of these 10 in. pizzas would be \pi (5)^2 or 25\pi.

We have two of these pizzas, so the total area that we would get with $14 would be 25\pi*2 or 50\pi.

For the second case, we have one pizza with a 14 in. diameter.

The area of this pizza will be \pi (7)^2 or 49\pi.

So for $15 we can buy 49\pi worth of pizza.

The best deal would be to buy the two medium pizzas of 10 inch diameter, because for $14, you get 50\pi.
