STEP 1

What is this asking? We need to find the slope of the line shown on the graph, using the "rise over run" method. Watch out! Be careful with the signs of the rise and run!
A downward movement is a negative rise, and a leftward movement is a negative run.

STEP 2

1. Find the rise.
2. Find the run.
3. Calculate the slope.

STEP 3

Alright, let's **start** with the **rise**!
This is the vertical change between the two points.
We're going from a y-value of 88 down to a y-value of 2-2.

STEP 4

Think of it like this: We're starting at 88 on the y-axis and moving down to 2-2.
How much do we move?
Well, that's 88 down to 00, and then another 22 down to 2-2.
That's a total downward movement of 8+2=108 + 2 = 10.
Since we're moving *downwards*, our **rise** is actually 10-10.

STEP 5

Now for the **run**!
This is the horizontal change between the two points.
We're starting at an x-value of 8-8 and going to an x-value of 22.

STEP 6

Visualize it: We're moving from 8-8 to 22 on the x-axis.
That's like moving 88 units to get to 00, and then 22 more units to get to 22.
So, we're moving a total of 8+2=108 + 2 = 10 units to the *right*.
Our **run** is +10+10.

STEP 7

Remember, the **slope** is just the **rise** divided by the **run**.
We found our **rise** to be 10-10 and our **run** to be 1010.

STEP 8

So, our **slope** is: riserun=1010 \frac{\text{rise}}{\text{run}} = \frac{-10}{10}

STEP 9

We can simplify this fraction by dividing both the numerator and denominator by 1010: 1010=101101=110110=111010=111=1 \frac{-10}{10} = \frac{-10 \cdot 1}{10 \cdot 1} = \frac{-1 \cdot 10}{1 \cdot 10} = \frac{-1}{1} \cdot \frac{10}{10} = \frac{-1}{1} \cdot 1 = -1 So, our **final slope** is 1-1!

STEP 10

The slope of the line is 1-1.
