Question

What are slope rules and stuff i need an explanation so i can write this in my notes. Thank you

Answer 1

Answer:

The slope of a line describes how steep a line is. Slope is the change in (y) values divided by the change in (x) values.

A lot of people remember slope as "rise over run" because slope is the "rise" (change in y) divided by the "run" (change in x).

Ratio of the vertical change (the “rise”) to the horizontal change (the “run”) between any  two points in a line.

The letter „m‟ is used to denote slope.

The slope will calculate to the same value for any 2 points on a line.

Positive slopes:

range increases as x

increases – line rises

from left to right

Negative slopes:

range decreases as x

increases – line falls

from left to right

Zero (0) slope:

horizontal lines have a

slope of 0 because the

difference of their y values is always 0

Undefined slope:

vertical lines have an

undefined slope because

the difference of the x values is always 0 (so we

can't divide!)
