4-98.
Graph the lines y = 2x − 3 and y = 2x + 1. Homework Help ✎
Where do they intersect?
Solve this system using the Equal Values Method.
Explain how your graph and algebraic solution relate to each other.
Do parallel lines ever intersect?
Set the equations equal to each other.
y = y
2x − 3 = 2x + 1
Subtract 2x from both sides. What happens?
What do the two methods have in common?
