Slope = y2-y1/ x2-x1
Here x1 is 4
Y1 is -7
X2 is 4
Y2is 8
Slope = 8-(-7)/4-4
= 15/0
Undefined
Answer: 3
Step-by-step explanation: To find the sum of these two numbers, remember that adding a negative is exactly the same thing as subtracting a positive. In other words, when we see 18 + (-15), we can change the problem so it's easier to understand and we will change in to 18 - 15.
Now, this is just basic subtraction.
18 - 15 = 3
Therefore, 18 + (-15) = 3

Answer:
Median- 12
Q1- 5
Q3- 43
IQR- 38
Step-by-step explanation:
2, 5, 11, 13, 43, 45
Put your numbers in order of least to greatest
Since there is no given median as the amount of numbers is even, find the number in between the 2 middle numbers, in this case, the number would be 12, as it is in between 11 and 13.
To find Q1 and Q3, you need to find the first and third median, which would be 5 and 43. To find the IQR, you need to subtract Q3 from Q1, which would give you 38 in this equation
You have 2 denominators so they need to be in the same family 5 and 10 are in the same family you take the biggest denominator and that is your common denominator and 3 + 1 =4 so 4/10 is your answer. (unless you need to simplify)
