What is the slope of the line?

Mathematics

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.

Answer:

34 minutes

Step-by-step explanation:

Given

Time\ Spent = 6

Phone\ Calls = 40

Required

Number of minutes left to spend (x)

Since there's only 1 minute left to spend on every other call;

Time left = x * 1

Time left = x

The required can further be calculated using:

Time\ Spent + Time\ Left = Phone\ Calls

This gives:

6 + x = 40

Subtract 6 from both sides

x = 40 - 6

x = 34

<em>Hence, there are 34 minutes left to spend</em>
