What is the slope of the line?

Mathematics
1 answer:
spin [16.1K]1 year ago
4 0

Answer:

-7/2

Step-by-step explanation:

The slope of a line can be defined as: \frac{rise}{run}, which can be more formally calculated as: \frac{y_2-y_1}{x_2-x_1}, where it's essentially the same thing, except the rise/run is being calculated with two points (which you already need)

So let's just say: (x_1, y_1)=(-5, 5)\text{ and } (x_2, y_2)=(-3, -2)

Plugging the values into the equation we get: \frac{-2-5}{-3-(-5)}\implies\frac{-7}{-3+5}\implies-\frac{7}{2}

You can also just look at the graph and see that from point 1 to point 2, it "rised" -7 units, and "ran" 2 units.

Notice how the "rise" is negative? That just means it went down.

Brooke saved the same amount of money each week for four weeks. She made this table to show how much money she saved.
Musya8 [376]

Answer:

In 10 weeks of time, Brooke would  earn $ 20.

Step-by-step explanation:

Here, according to the table:

The money saved in week 1   =  $ 2   =   $(1  x 2)

The money saved in week 2  =  $ 4   =  $ ( 2 x 2)

The money saved in week 3   =  $ 6  =  $ ( 3 x 2)

The money saved in week 4   =  $ 8 =   $ ( 4 x 2)

So, by the graph relation, we can see that:

The amount saved in n weeks = ( n x 2) dollars

So, the amount saved by Brooke in 10 weeks is:

Put n =  10, we get:

The money saved  = 2 n = 2 x 10 = $ 20

Hence, in 10 weeks of time, Brooke would  earn $ 20.
