Lesson Plan

Write the equation of a line in slope-intercept, point-slope or standard form from a slope and a point, two points, or a graph, and convert it among the three forms

Read the slope and $y$-intercept from an equation (the coefficient of $x$ in slope-intercept form, $-A/B$ in standard form) and use them to match the equation to its graph

Write the equation of a horizontal or vertical line ($y = k$ or $x = h$), and explain from the equation which way the line runs

Choose the form of a linear equation that reaches what a question asks for in the fewest steps

Determine the slope of a line from points or a graph (Geometry, 24–27) — context only; owned by act-geo-coord-slope, not an anchor of this brief AF 503. Match linear equations with their graphs in the coordinate plane (Algebra/Functions, 24–27)
