What is an equation of the line that passes through the points (4,-2) and (8,3)?

Equation: Y = 5/4x -7

Step-by-step explanation:

y2 - y1

              < This is your slope equation

x2 - x1

3 - (-2)

8 - 4

3 + 2

8 - 4

5

    <    This is your slope

4

Y = mx+b            < Your second equation

3 = 5/4 (8) + b                 < Your new equation

3 = 10 + b                 < You times 5 by 10 and then divide it by 4

- b + 3 = 10                   <    Subtract  b

- b = 7                             < Subtract  3

b = -7                                  < switch the negative sign

Your equation will be:

Y = 5/4 -7

Hope that helps! :)

go on the tube you might find some information there

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
