Identifying Intercepts and Graphs

The video tutorial covers the process of matching equations to their corresponding graphs. It begins with an introduction to the topic, followed by a detailed explanation of x and y intercepts. The tutorial then demonstrates how to test specific points on graphs to determine which equation they correspond to. Finally, it uses logical deduction to match equations with graphs, emphasizing the importance of understanding intercepts and testing points.

What is the first step in matching equations to their graphs?

• Drawing the graph

• Labeling the axes

• Identifying the slope

• Putting a date on your notes

What is the x-intercept of a graph?

• Where the graph crosses the y-axis

• The lowest point on the graph

• Where the graph crosses the x-axis

• The highest point on the graph

How can you find the x-intercept of an equation?

• Set x to zero

• Set y to zero

• Find the slope

• Find the y-intercept

What is the y-intercept of a graph?

• Where the graph crosses the x-axis

• Where the graph crosses the y-axis

• The lowest point on the graph

• The highest point on the graph

What is a common mistake when identifying intercepts?

• Forgetting to label the graph

• Not plotting enough points

• Using the wrong equation

• Confusing x and y values

What should you do if you make a mistake identifying intercepts?

• Ignore it

• Start over

• Be aware and correct it

• Ask for help

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

• (0, 3)

• (3, 0)

• (0, -3)

• (3, 3)

Which point is used to test if it lies on the graph of y = 3x + 3?

• (3, 0)

• (0, 3)

• (0, -3)

• (3, 3)

What is the result when testing the point (3, 0) on y = 3x + 3?

• It matches

• It does not match

• It is the y-intercept

• It is the x-intercept

What conclusion can be drawn if a point does not match an equation?

• The point is incorrect

• The equation is incorrect

• The graph matches the equation

• The graph does not match the equation
