1. When two linear equations are graphed on the same coordinate plane, what does their point of intersection represent?
The sum of the x-intercepts
A solution that satisfies only one equation
The solution that satisfies both equations simultaneously
The y-intercept of the first equation
2. If two linear equations have the same slope but different y-intercepts, how will their graphs appear?
Intersecting at one point
Coinciding lines
Parallel lines
Perpendicular lines
3. The solution to a system of two linear equations is the point where their graphs .
4. If two equations represent the same line, they have many solutions.
5. Graph the following system of equations and find the solution. Label your lines clearly.
Equation 1: y = 2x - 3
Equation 2: y = -x + 3
