Read each question carefully and follow the instructions. For graphical questions, use the provided coordinate plane to draw your lines and identify the intersection point.
1. Graph the following system of linear equations on the coordinate plane below and find the solution:
Equation 1: y = 2x - 1
Equation 2: y = -x + 5
Solution (x, y):
2. Graph the following system of linear equations and determine if there is one solution, no solution, or infinitely many solutions:
Equation 1: x + y = 4
Equation 2: 2x + 2y = 8
Type of solution:
3. Which of the following systems of equations would have no solution when graphed?
y = 3x + 2 y = 3x - 1
y = x + 4 y = -x + 4
y = 2x + 3 y = 2x + 3
y = -5x y = 5x
4. True or False: The solution to a system of linear equations is the point where the lines intersect.
True
False
5. When two lines are parallel and distinct, their system of equations has solutions.
6. Consider the system of equations:
Equation 1: y = x + 3
Equation 2: y = -2x
Without graphing, explain how you would determine the solution to this system.
