What is the slope of the line

The slope is 0.8 or 4/5.

Step-by-step explanation:

Let's take two points on a line. (-2,0) and (3,4).

Now, determine the rise and run.

Slope = Rise/Run

Conclusion:

Therefore, the slope is 0.8 or 4/5.

Hoped this helped.

(a) the volume of the cone is 20/3 in3

hence, option a is correct.

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
