Solve a system of equations by graphing slope intercept

The video tutorial explains how to graph equations in slope-intercept form, focusing on understanding the slope and Y-intercept. It provides examples of graphing lines, finding intersections, and correcting errors. The tutorial emphasizes the importance of graphing for solving systems of equations and highlights the concepts of slope as a ratio and Y-intercept as the point where the line crosses the Y-axis.

What does the 'B' represent in the equation Y = MX + B?

• The X-intercept

• The slope of the line

• The Y-intercept

• The origin

How can you express a whole number slope as a ratio?

• By writing it as a fraction over 1

• By multiplying the number by 10

• By adding 1 to the number

• By dividing the number by 2

What is the first step in graphing a line using the slope-intercept form?

• Plotting the X-intercept

• Calculating the slope

• Drawing a horizontal line

• Plotting the Y-intercept

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

• The system is dependent

• The system has one solution

• The system has no solution

• The system is inconsistent

If a line has a slope of -3, how can you move from one point to another on the graph?

• Down 3 units and right 1 unit

• Down 3 units and left 1 unit

• Up 3 units and left 1 unit

• Up 3 units and right 1 unit
