Learn how to graph lines with two methods: using x- and y-intercepts and using point-slope form. First, solve for x- and y-intercepts to graph a line. Then, identify an ordered pair from a linear equation in point-slope form to graph a line using this point and the slope. This is the third of seven activities for teaching and learning linear equations in algebra: *Ski Slope*; *y=mx+b*; ** Points, Intercepts, and Slopes, Oh My!**;

*Linear Word Problems*;

*Solving Systems of Equations by Graphing*;

*Systems of Equations Word Problems Part 1*;

*Systems of Equations Word Problems Part 2*.

**CCSS.Math.Content.HSA-CED.A.2** Create equations in two or more variables to represent relationships between quantities; graph equations on coordinate axes with labels and scales.

**CCSS.Math.Content.HSA-REI.D.10** Understand that the graph of an equation in two variables is the set of all its solutions plotted in the coordinate plane, often forming a curve (which could be a line).

**CCSS.Math.Content.8.F.B.4** Construct a function to model a linear relationship between two quantities. Determine the rate of change and initial value of the function from a description of a relationship or from two (x, y) values, including reading these from a table or from a graph. Interpret the rate of change and initial value of a linear function in terms of the situation it models, and in terms of its graph or a table of values.
