Answer:
1.) {Slope} Run=A Rise=B (any letter can be used instead of A and B.)
B=(x1,y1) A=(x2,y2)
B=(2,1) A=(0,-3)
Rise=4 Run=2 this creates 4/2
4/2=2
How to check your work:
m=x2-y2/x1-y1
m=1+3/0-2 (the negative in -3 changes to a positive so it's now addition. Without changing the appearence to addition, it would still mean the same thing, it would look like this, 1- -3 the two negatives cancel eachother out.)
1+3/0-2=4/2=2 (this is the same as the answer above so it's correct, 2 is the slope.)
Step-by-step explanation:
Slope=rise/run
Rise/run=y/x
Y/x=y2-y1/x2-x1
(Rise means how many units you move up or down from point to point. On the graph that would be a change in the y values. Run means how far left or right you move from point to point.)
Every straight line can be represented by y=mx+b
m=slope
b=y-intercept
Calculating y-intercept:
(The y-intercept is the value of y at the point where the line crosses the y-axis.)
The y-intercept is (0,-3) because that's where the line crosses.
I'm sorry if this is confusing, but I hope this helps you get the other two answers!

Answer:
The arrangement of the given equation in the slope - intercept form are
1.
Step-by-step explanation:
Given:
Let A ≡ ( x1 , y1 ) ≡ (-12 , 70)
B ≡ ( x2 , y2 ) ≡ (-4 , 78)
Slope - intercept form :
Where,
m is the slope of the line.
c is the y-intercept.
When two points are given say ( x1 , y1 ) and ( x2 , y2) we can remove slope by
Slope,
∴
Now equation of a line for a point ( x1 , y1 ) and having slope m is given as,
Which is in the required form
y = 1x + 82
Intercepts: Where the line cut X axis called X- intercept and where cut Y axis is called Y- intercept.
Outlier is the value in the data set which very different from the other values.the difference between the mean of the data, including the outlier and excluding the outliers 0.93. Thus the option 3 is the correct option
Given information-
Shelly runs a 5 k race on the first of each month.
<h3>Mean and Outlier</h3>
Mean is the addition of the given data divided by the total number of the values. Outlier is the value in the data set which very different from the other values.
Total values are 12.The addition of all the values is,
Thus the mean including the outlier for the given data is,
The value 50.32 is much bigger than the other data set. Thus 50.32 is a outlier for the given problem. The addition of all the values excluding the outlier is,
Now the total values are 11. Thus the mean excluding the outlier is,
The difference,
Thus the difference between the mean of the data, including the outlier and excluding the outliers 0.93. Thus the option 3 is the correct option.
