Hey there,
The slope is the rise over the run of a line right?
And the formula is y2-y1 as the numerator and x2-x1 as the denominator.
So in this case the two xs are 1 and 2 right?
And the denominator is the second denominator is the second x minus the first x right?
In this case the second x is 2 roght?
And the first x is 1.
So it’s 2-1 which is 1.
So the answer is x2-x1 which is 1
Hope this helps

Answer:
Step-by-step explanation:
Step 1: Minimum= 21 Maximum= 87
Step 2: Range minimum= 20
Step 3: Range maximum= 90
Step 4: Range 90-20= 70
Answer: -48
Step-by-step explanation:
When your subtracting negatives you go farther from zero. When you add negatives still go farther from zero but, when you have a negative number with a positive number it will be a 50% chance you'll get a positive number.
For example: -2 - (-5) = -7
Example 2: -10 + 20 = -10
How? 20 is more than -10 therefore when you count 20 from -10 u get 10.
Sub x= 0.3
5(0.3) + 2y = 20
2y =20-1.5
Y= 9.25
Ans= 9.25
25 - 17 = 8
8/4 = 2
It is 2 standard deviations away from the mean (average).
