What is the slope of JK? J=(2, 4), K(6, 1), L(2, -2), M(-2, 1)

-3/4

Step-by-step explanation:

First, we find the change in x & change in y.

Change in x: 6 - 2 = 4

Change in y: 1 - 4 = -3

Since slope is rise (change in y) over run (change in x),

-3/4 is the slope.

data plot with   3 dots over 33, 1 dot over 34, 2 dots over 35, no dot over 36, 1 dot over 37, 2 dots over 38, 4 dots over 39, and 2 dot over 40.

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
