Question

Which of the following are accurate expressions for slope

Answer 1

m = (y₂-y₁)/(x₂-x₁)

m= Slope
(x₁,y₁) (x₂,y₂)

Answer 2

Answer: if you have a function two sets of points (Y1,X1) and (Y2,X2), then the slope that connects this two sets is A=
`((Y2 -Y1))/(X2 - X1)`

then Y1 =
`((Y2 -Y1))/(X2 - X1)`*X1 + b

and Y2 =
`((Y2 -Y1))/(X2 - X1)`*X2 + b

where b is a random real constant, called the y-intercept.
