Lesson 9 is a continuation of Lesson 8 but presents equations in standard form that are then written into slope-intercept form as a strategy to graph.
If you need to adapt or shorten this lesson for remote learning, we suggest prioritizing Anchor Problems 2 and 3 (benefit from worked examples). Find more guidance on adapting our math curriculum for remote learning here.

Given the equation $${2x+3y=9}$$, determine the slope and $$y$$-intercept, and then graph the line that represents the equation.
Write the equation below into slope-intercept form and then graph the line that represents the equation.
$${-4x-2y=-5}$$
Match each equation to a graph. Be prepared to explain your reasoning.
Equation A: $${ y=5}$$
Equation B: $${x=5}$$
