8.EE.C.8
Solve two equations at once — the answer is where the lines cross.
Worksheets for this standard 2 topics
The standard, officially
Analyze and solve pairs of simultaneous linear equations.
This standard has parts
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.8.EE.C.8a
b
Solve systems of two linear equations in two variables algebraically, and estimate solutions by graphing the equations. Solve simple cases by inspection. For example, 3x + 2y = 5 and 3x + 2y = 6 have no solution because 3x + 2y cannot simultaneously be 5 and 6.8.EE.C.8b
c
Solve real-world and mathematical problems leading to two linear equations in two variables. For example, given coordinates for two pairs of points, determine whether the line through the first pair of points intersects the line through the second pair.8.EE.C.8c
