Study Notes
Systems of Equations
- The point of intersection represents the solution to a system of equations, where both equations are satisfied.
Conditions for Infinite Solutions
- A system of equations can have infinitely many solutions when the two equations are identical.
Elimination Method
- The elimination method is used to find the point of intersection of two linear equations by canceling out one variable.
Example of Point of Intersection
- The point of intersection of the linear equations y = -9x + 7 and y = 3x - 4 can be found by solving the system of equations.
Parallel Lines
- When two linear equations have the same slope but different y-intercepts, they are parallel lines and have no point of intersection.
Substitution Method
- The substitution method uses the slope-intercept form (y = mx + b) of the equation.
Solution to a System of Equations
- The solution to a system of equations is the point of intersection, where both equations are satisfied.
Infinite Solutions
- A system of equations will have infinite solutions when the two equations are identical.
Graphical Representation
- The number of solutions can be determined using a graph by looking at the number of points of intersection between the two lines.
