Learning Target:
I can estimate solutions to a system of equations by graphing when both equations are in slope-intercept form.
CCSS:
8.EE.5 Graph proportional relationships, interpreting the unit rate as the slope of the graph.
8.EE.8 Analyze and solve pairs of simultaneous linear equations.
a) Understand that solutions to a system of two linear equations in two variables correspond to points of intersection of their graphs, because points of intersection satisfy both equations simultaneously.
