Answer:
-8/9 yw
Step-by-step explanation:
just divide the numbers by each other:D
The standard form of a line:
.
The point-slope form: ![y-y_1=m(x-x_1)](https://tex.z-dn.net/?f=y-y_1%3Dm%28x-x_1%29)
We have the point (3, -1) and the slope m = -1. Substitute:
![y-(-1)=-1(x-3)](https://tex.z-dn.net/?f=y-%28-1%29%3D-1%28x-3%29)
<em>add x to both sides</em>
<em>subtract 1 from both sides</em>
![\boxed{x+y=2}](https://tex.z-dn.net/?f=%5Cboxed%7Bx%2By%3D2%7D)
Answer:
Yes
Step-by-step explanation:
As long as the slopes of these two lines are not the same, they will intersect.
Given two points on a line, we can find the slope by taking the difference in the y coordinates and dividing it by the difference in the x coordinates.
Slope of 1st line: ![\frac{-5-1}{-1-2} =\frac{-6}{-3} =\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B-5-1%7D%7B-1-2%7D%20%3D%5Cfrac%7B-6%7D%7B-3%7D%20%3D%5Cfrac%7B1%7D%7B2%7D)
Slope of 2nd line: ![\frac{-6-2}{-1-1} =\frac{-8}{-2}=4](https://tex.z-dn.net/?f=%5Cfrac%7B-6-2%7D%7B-1-1%7D%20%3D%5Cfrac%7B-8%7D%7B-2%7D%3D4)
The slopes are not equal, therefore the lines intersect.
If they do not have a line of best fit this may be because there is no correlation
Hello!
We have two probabilities we can use; we have 170/400, for our experiment, and 1/2, which is our theoretical probability.
To solve, we just multiply the two probabilities.
=0.2125≈21.3
Therefore, we have about a 21.3% chance of this event occurring.
I hope this helps!
