UNIT 2 LESSON 4 - DEVELOPING POINT SLOPE FORM
WRITING THE LINEAR FUNCTION
![WRITING THE LINEAR FUNCTION](https://www.geogebra.org/resource/yype5nqc/nJXdSDYPguL5lWKB/material-yype5nqc.png)
What is the slope of the line?
What is the y-intercept?
Because we do not have an integer as the y-intercept all of the time, we need to know how to get the equation for a line a different way.
So how do we write equations for these graphs?

What is the slope of the line in the graph?
What would the equation be in point-slope form if you were using the point (-7,0)
Solving for y to get the equation in slope-intercept form would be...
What would the equation be in point-slope form if you were using the point (9,-4)
Solving for y to get the equation in slope-intercept form would be...
Does it matter which point you use to write your equation in point-slope form? Explain why or why not.
