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

Front

What is the solution to a system of equations represented graphically?

Back

The solution is the point where the two lines intersect.

Front

What does a solid line indicate when graphing an inequality?

Back

A solid line indicates that the inequality includes 'or equal to' (≥ or ≤).

Front

What is the relationship between the slopes of parallel lines?

Back

Parallel lines have the same slope but different y-intercepts.

Front

How many solutions do parallel lines have?

Back

Parallel lines have no solutions.

Front

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

Back

It means that the shaded regions do not overlap.

Front

What is the solution to a system of equations if the lines are the same?

Back

There are infinitely many solutions.

Front

What is the graphical representation of a system of inequalities?

Back

It is represented by shaded regions on a graph.

Front

How can you determine if a point is a solution to a system of inequalities?

Back

Substitute the point into each inequality to see if it satisfies all of them.

Front

What does it mean if a system of equations has exactly one solution?

Back

It means the lines intersect at a single point.

Front

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.
