Answer:

Step-by-step explanation:
Given
- 
The LCM of 4 and 5 is 20
= 
= 
Answer:
The answer is: m = 3/2
Step-by-step explanation:
The slope m = (y - y1)/(x - x1]
Replace the variables with the points given:
m = (2 - 5)/(1 - 3)
m = -3/-2
m = 3/2
If this is asking how to write this as a complex fraction, here's how:
First, do the whole number (4) multiplied by the diameter (4) to get 16. Then you take 16 and add this to the numerator (1) to get 17. Then your final answer is this number (17) over the original denominator (4), or 17/4
Hope this helps :)
