2. Students will be able to demonstrate their understanding of writing linear equations in 1) point-slope form, 2) slope-intercept form given two points, a graph, and a point and a slope by scoring at least basic on their exit slip. Objective

3. Standard 6.0 Students graph a linear equation and compute the x- and y-intercepts (e.g., graph 2x + 6y = 4). They are also able to sketch the region defined by linear inequality. Standard 7.0 Students verify that a point lies on a line, given an equation of the line. Students are able to derive linear equations by using the point- slope formula.

5. 1) Write an equation in slope-intercept form of the line with a slope of ¼ and a y-intercept of –6. 2) Write an equation in slope- intercept form of the line shown in the graph. 3) Write an equation of a line that passes through (2, –3) with slope ½.
