Question

Briefly explain the concept of a slope. If one line has a slope of 2 and another has a slope of -4, which line is steeper?

Answer 1

Answer:

The steepness of a hill is called a slope. The same goes for the steepness of a line. The slope is defined as the ratio of the vertical change between two points, the rise, to the horizontal change between the same two points, the run.

One definition of slope is: "rise over run, which means how far does is rise or fall vertically, for a unit horizontally,

A slope of -3, it fell 3 units vertically for one unit horizontally

A slope of +2, it rose 2 units vertically for one unit horizontally

;

Obviously, -3 is steeper than +2
