Question

Write at least three different expressions that mean “slope”

Answer 1

1. y^2 - y^1 over x^2 - x^1
2. y=mx+b
3. rise over run

Answer 2

Explanation:

Considering 'm' as the slope of a function y=f(x) we can have:

1. m=(y2-y1)/(x2-x1) which is the slope of a line based on two points from the line.

2. m=dy/dx which is the slope of the function y=f(x) in (x,y) by the derivative.

3. m=tan(Ф) which is the slope of a line when the angle (Ф) with respect x-axis is known.
