Answer:
Slope: -1
y-intercept: 6
Step-by-step explanation:
Lets figure out the slope with the formula, . Take 2 coordinates and substitute them in. Lets take (-3,9) and (-1,7). Here are the steps:
Now we know that the slope is -1, so m = -1.
Lets figure out the y-intercept. We have to have an equation with the slope in it. Since we don't know the y-intercept yet, we will use the equation y = -x + b. Lets take the coordinate (5,1). Substitute the coordinates in. Here are the steps:
1 = -5 + b
b = 6
Now we know that the y-intercept is 6, so b = 6. I hope this helped!

<h3>QUESTION</h3>
Write<em> 3 apples for every 8 oranges</em> as a ratio in 3 different ways
There are 3 ways to write a ratio:
- Fraction
- "to"
- :
First let's write it as a fraction.
To write it as a fraction, you make the first thing as the numerator(top number) and the second thing as the denominator(bottom number).
3 apples for every 8 oranges
The first thing is 3 apples. That means the numerator will be 3. The second thing is 8 oranges. That means the denominator will be 8. Here is your fraction:
Now let's write it using the word "to".
To write it using "to", you write the first thing, then "to", then the second thing. In this question, the first thing is 3 apples. The second thing is 8 oranges. Your phrase will be:
3 apples to 8 oranges
At last, let's write it using a colon.
To write it using a colon, you do the same thing you did when writing it with "to", but you change the "to" with a colon.
3 : 8
Here are your 3 answers:
- 3 apples to 8 oranges
- 3 : 8
