Graphing Systems of Equations Mastery

The video tutorial covers graphing systems of equations, focusing on identifying solutions by finding where lines intersect. It explains the concept of parallel lines, no solution, and infinite solutions through graphing examples. The tutorial uses the slope-intercept form to plot equations and demonstrates how to determine solutions by analyzing the intersection points of the lines.

What does it mean when two lines on a graph intersect?

• The lines are parallel.

• There are infinitely many solutions.

• There is one solution.

• There is no solution.

What is the y-intercept of the equation y = 11/2x + 5?

• 0

• 5

• 2

• 11

If two lines have the same slope but different y-intercepts, what can be said about them?

• They are perpendicular.

• They have infinitely many solutions.

• They are parallel.

• They intersect at one point.

What is the slope of the line y = -8/3x - 7?

• 7

• 8/3

• -8/3

• -7

Where do the lines y = -8/3x - 7 and y = -1/3x + 7 intersect?

• (6, -9)

• (-6, 9)

• (-9, 6)

• (9, -6)

What is the y-intercept of the equation y = -1/3x + 7?

• 1/3

• -1/3

• 7

• -7

What does it mean when two lines on a graph are identical?

• There is no solution.

• There is one solution.

• There are infinitely many solutions.

• The lines are parallel.

What is the slope of the line y = 2x - 5?

• -5

• 2

• 1/2

• -2

If two lines have the same slope and the same y-intercept, what can be said about them?

• They intersect at one point.

• They have infinitely many solutions.

• They are perpendicular.

• They are parallel.
