Point-Slope Form of a Line - General Discussion. This is your best equation-building tool. It frees you from the messiness of slope-intercept form for the purpose of building an equation of a line.

Exercise #1 - Slope

Exercise #2 Slope-Intercept form. Parallel and Perpendicular Lines.

Exercise #3 Point-Slope Form

Exercise #4 Analyze (and graph) the General Form of a Line. Intercept Method for graphing is on every test...

Exercise #5 Horizontal Line

Exercise #4 Vertical Line

Exercise #7 Questions about Horizontal and Vertical Lines

Exercise #8 Graph Horizontal and Vertical Lines

Exercise #s9 - 12 Slope Calculations

Exercise #13 Find Slope from a Graph

Exercise #14 Graphing lines through the origin

Exercise #15 Find an equation of a line from its graph. I encourage you to use Point-Slope Form the way I suggest: y = m(x - x₁) + y_{1. WebAssign should accept that
form without any further simplifying. This is also the preferred form on tests.}

Exercise #18 Find the Equation of a Line, given the slope and the y-intercept.

Exercise 20 Find an Equation of the Line, given its slope and an arbitrary point. My method for Point-Slope is the slickest. WebAssign will accept point-slope form for these, any time it asks for an equation of the line, without specifying. I will always prefer point-slope formulation for these type questions.

Exercise #23 Find an Equation of a Line, Given Two Points on the Line. Again, Point-Slope is the tool

Exercise #s 26 and 27 Horizontal and Vertical Lines

Exercise #s 28 - 30 Parallel and Perpendicular Lines

Exercise #31 Equation of a Parallel Line

Exercise #32 Equation of a Perpendicular Line

Exercise #33 Slope-Intercept Method. Ugh... I'm less interested in this than the Intercept Method and Point-Slope Form of a Line. Slope-Intercept is what they drill and kill on in Algebra 1 in high school.

Exercise #s 35 - 37

Exercise #18
