M=3

-EXPLANATION-
Slope=rise over run(rise/run)
I used the points (-1,-6) and (2,3)
To solve you will use this formula: m=y₂−y₁/x₂−x₁
3=y2
2=y1
-6=x2
-1=x1
——————-
Set it up like so:
3- -6/2- -1

3- (-6)= 9

2- (-1)=3

9/3

9 divided by 3 is 3, making your slope(m) 3

sarah said 0.00001 is bigger than 0.001 because the first number has more digits to the right of the decimal point is sarah corr
prisoha [69]
If Sarah things 0.00001 is bigger than 0.001, then let's try it! I am not going to tell you the exact answer, but I am going to help you solve this problem. Ok. So .00001 is one hundred thousandths of something. .001 is a thousandth of something. So which one would be smaller? Chopping a watermelon (random example) in one hundred thousand pieces or chopping a watermelon into a thousand pieces?
