## WRITING THE LINEAR FUNCTION

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?

## POINT SLOPE FORMULA

## USING POINT SLOPE FORM PRACTICE

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.
