Lessons that teach this standard

• How to Graph Linear Equations

  Graph a line three ways — from slope-intercept form, from intercepts, or from a table — and understand why every point on the line is a solution.

• Slope-Intercept Form: y = mx + b

  Understand y = mx + b, what m and b each control, how to graph a line from it in two moves, and how to rewrite any linear equation into this form.

• Standard Form of a Linear Equation: Ax + By = C

  What standard form is, when it beats slope-intercept form, how to convert between the two, and how to find the slope without rearranging.

• x-Intercepts and y-Intercepts: Finding Where a Line Crosses

  Find the x- and y-intercepts of any equation by setting the other variable to zero, why that works, and what intercepts mean in a real situation.
