Graphing a system of equations when you have infinite many solutions

The video tutorial explains how to solve systems of inequalities by graphing. It covers converting equations to slope-intercept form, graphing them, and identifying intersections. The instructor demonstrates solving for Y, graphing using slope and intercept forms, and highlights common mistakes. The tutorial concludes with a realization that two equations are identical, leading to overlapping graphs.

What is the first step in solving a system of inequalities by graphing?

• Convert the equations to slope-intercept form

• Convert the equations to standard form

• Identify the X-intercept

• Find the intersection point

When graphing a line with a negative slope, which of the following is true?

• The slope is negative only if the denominator is negative

• The slope is negative only if the numerator is negative

• The slope is always positive

• The slope can be positive if both numerator and denominator are negative

How do you determine the X-intercept when using the intercept method?

• Set Y to zero and solve for X

• Set X to zero and solve for Y

• Use the slope to find the intercept

• Find the midpoint of the line

What mistake did the teacher realize when using the intercept method?

• The Y-intercept was not found

• The slope was calculated incorrectly

• The equations were identical

• The equations were not in standard form

What is the significance of the intersection point in a system of inequalities?

• It represents the solution to the system

• It is where the graph starts

• It is the midpoint of the line

• It is the highest point on the graph
