Answer:
Your slope would be -5/3
Step-by-step explanation:
To find the slope from two points, you would use the formula y2-y1/x2-x1
In this case, the equation would look like -12-8/3-(-9)
-12 - 8 = -20
3 - (-9) = 12
-20/12 = -5/3
Remove the decimal and put the number over 1000 or the next highest mark(10,100,1000,10000,etc depending on how many figures are in the number)
226/1000
Then divide the two by the Greatest Common Factor. In this case, it will be 2.
113/500
You cannot divide this any further because 113 is a Prime number, and 500 is not divisible by 113.
