Front

What is the solution to the system of equations represented by the graph?

Back

(6, -2)

Front

Solve for x and y: y = 2/3x - 2 and y = -x + 3.

Back

(3, 0)

Front

If a system of linear equations has infinitely many solutions, what does this mean about the two lines?

Back

Same line.

Front

What is the solution to the equation represented by the point?

Back

(1, -1)

Front

What does it mean if two lines are parallel in a system of equations?

Back

They have no solutions.

Front

What is the graphical representation of a system with one solution?

Back

Two intersecting lines.

Front

How can you determine the solution of a system of equations graphically?

Back

By finding the point of intersection of the lines.

Front

What is the slope of the line represented by the equation y = 2/3x - 2?

Back

2/3.

Front

What does the y-intercept represent in a linear equation?

Back

The point where the line crosses the y-axis.
