What is the equation of the line in slope-intercept form?

ANSWER

The equation of the line in slope-intercept form is



EXPLANATION

The slope intercept form of a line is given by

Where is the slope and
is the y-intercept.

We can read any two points from the graph and use it to determine the slope of the line.

For instance, the graph passes through the points
and

The slope can be found using the formula,



This implies that,







Also the y-intercept is



Therefore

We substitute all these values in to the above equation to obtain,
