Ragan - Unit 3 Review: Solving Systems of Equations/Inequal.

Front

What is a system of equations?

Back

A system of equations is a set of two or more equations with the same variables. The solution is the point(s) where the equations intersect.

What does it mean for two lines to be parallel in the context of systems of equations?

Back

Two lines are parallel if they have the same slope but different y-intercepts, meaning they will never intersect and thus have no solutions.

What is the solution to the system of equations y = 2x + 1 and y = 4x - 1?

Back

The solution is the point (1, 3), where the two lines intersect.

What is the significance of the y-intercept in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, representing the value of y when x is zero.

What does it mean for a point to be a solution to a system of inequalities?

Back

A point is a solution to a system of inequalities if it satisfies all the inequalities in the system, meaning it lies in the shaded region of the graph.

What type of line is used when graphing inequalities with < or >?

Back

A dotted line is used when graphing inequalities with < or > to indicate that points on the line are not included in the solution.

What is the difference between < and ≤ in inequalities?

Back

The symbol < indicates that the value is strictly less than, while ≤ indicates that the value can be less than or equal to.

Front

What does it mean if a system of equations has no solution?

Back

A system of equations has no solution if the lines are parallel, meaning they do not intersect at any point.

What is the graphical representation of a system of inequalities?

Back

The graphical representation of a system of inequalities consists of shaded regions that represent all possible solutions, along with boundary lines.
