What is the slope of line m? On a coordinate plane, a straight line goes through (negative 2, 1), (0, 0), and (2, negative 1).

Given:

A straight line goes through (-2,1), (0,0), and (2,-1).

To find:

The slope of the given line.

Solution:

Slope formula

Consider any two points from the given points.

The line goes through (-2,1) and (0,0). So, the slope of the line is

Therefore, the slope of the line is .

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
