How to solve a system by graphing with a horizontal line

The video tutorial demonstrates how to solve a system of equations by graphing. It begins with setting up the X and Y axes and using a table method to graph the equation Y = -1, resulting in a horizontal line. The tutorial then explains graphing using the slope-intercept form for another equation, identifying the intersection point of the two lines as the solution. The solution is consistent and independent, as the lines intersect at a single point.

What is the main challenge students face when graphing Y = -1?

• Graphing with only one variable

• Finding the Y-intercept

• Choosing the correct X values

• Understanding the slope

In the slope-intercept form Y = MX + B, what does 'B' represent?

• The slope of the line

• The point of intersection

• The Y-intercept

• The X-intercept

How do you determine the slope from the equation Y = -3X + 5?

• By calculating the rise over run

• By finding the constant term

• By looking at the coefficient of X

• By identifying the Y-intercept

What does it mean if two graphs intersect at a single point?

• The system has no solution

• The system has infinitely many solutions

• The system is consistent and independent

• The system is inconsistent

What is the solution to the system of equations if the graphs intersect at (2, -1)?

• The solution is (1, 2)

• The solution is (2, -1)

• The solution is (-1, 2)

• The solution is (0, 0)
