Solving a system using graphing

The video tutorial covers graphing linear equations in slope-intercept form, Y = MX + B. It explains how to rearrange equations to isolate Y, graph them, and find intersection points. The tutorial emphasizes understanding the slope and Y-intercept, plotting points, and connecting graphs to solve equations graphically.

What is the primary form used for graphing linear equations?

• Standard form

• Point-slope form

• Quadratic form

• Slope-intercept form

How do you isolate y in the equation 2x + y = 3?

• Subtract 2x from both sides

• Divide both sides by 2

• Multiply both sides by 2

• Add 2x to both sides

What is the y-intercept of the equation y = 1/2x - 9/2?

• -9

• -4.5

• 9

• 4.5

How do you determine the slope from the equation y = 1/2x - 9/2?

• The x-intercept

• The coefficient of x

• The constant term

• The y-intercept

What is the slope of the equation y = -2x + 3?

• -2

• -1/2

• 2

• 1/2

What is the intersection point of the graphs of the given equations?

• (3, -3)

• (-3, -3)

• (-3, 3)

• (3, 3)

What does the intersection point of two graphs represent?

• The y-intercept of both lines

• The x-intercept of both lines

• The solution to the system of equations

• The midpoint of the lines
