...d if a point lies on a line by plugging in correct x and y values 5) Writing an equation in slope-intercept form. Materials: hand out Motivation: Since everyone knows the key ingredients of writing an equation in slope intercept from what do you think are the key ingredients of writing an equation in point slope form? Development: 1) Question: Who can remind us of the key ingredients of writing an equation in slope intercept form? 2) Question: What do you think are the key ingredients of writing an equation in point slope form? 3) I would tell the students that point slope form of a line is 4) Question: Who can tell us how to write the equation for the line that passes through point (-3, 5) and has a slope of -3/4 5) Question: Remembering what the key ingredients for our new formula is, does anyone think they can write an equation in point slope form of a line that passes through (-8,3) and (4,5) 6) Question: Why do we need this form of an equation when it seems more difficult then the slope intercept form? 7) Work on the hand out Summary: What are our key ingredients of writing an equation in point slope form? When you are told to write an equation in point slope form and you are given two points which poi...
