I need it rnnn pleaseee

see explanation

Step-by-step explanation:

Calculate the slope m using the slope formula

m =

with (x₁, y₁ ) = (8, - 3) and (x₂, y₂ ) = (2, 6)

m = = = -

------------------------------------------

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

y = 5 - 2x , that is

y = - 2x + 5 ← in slope- intercept form

with slope m = - 2

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
