Please help solve question 12 and through 14

( will give brianlst :))

12. The slope is 2

    The y-intercept is 5

13. The slope is 1

     The y-intercept is 5

14. The slope is 0.99

     The y-intercept is 10

Step-by-step explanation:

12. If you use the rise over run method you go up by 2 and over 1. If you put rise over run you get 2/1 and that is equal to 2. So, slope is 2. The y-intercept is where x=0. If you look you can see that when x is 0, y is equal to 5. Therefore, the y-intercept is 5.

13. The slope is 1 because if you use the slope formula you can use two points like (1,6) and (2,7) in it to find that the slope is 1. You can also see that both the x and y variables go up by 1 each time, so the slope has to be 1. Once again the y-intercept is where x equals 0, even though it isn't shown on the graph we can infer it. At 0 days, the length of the kudzu would be 5 (because 5 is one step less than 6, remember the slope is 1).

14. The slope would have to be 0.99 because each consecutive download is 99 cents. There is a base membership fee of $10 so that has to be the y-intercept.

I hope this helps!!

If you have any questions let me know!

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
