Understanding Graph Intercepts

The video tutorial explains how to determine horizontal and vertical intercepts of graphs, represented as ordered pairs. It covers the process of identifying these intercepts on the axes, using examples to illustrate the concepts. The tutorial also addresses cases where intercepts do not exist, instructing to use 'DNE'.

What is the format of an ordered pair?

• x, y in parentheses

• y, x in parentheses

• y, x in square brackets

• x, y in square brackets

Where do we find the x values or inputs on a graph?

• At the origin

• Along the horizontal axis

• Along the diagonal axis

• Along the vertical axis

What is the x value of a vertical intercept?

• Depends on the graph

• Always one

• Always zero

• It varies

In the first graph, what is the y value of the vertical intercept?

• Negative four

• Zero

• Positive four

• Two

How many horizontal intercepts does the first graph have?

• None

• Three

• Two

• One

What is the ordered pair for the left horizontal intercept in the first graph?

• Negative two, zero

• Zero, negative two

• Zero, two

• Two, zero

In the second graph, what is the y value of the vertical intercept?

• Zero

• Negative two

• Positive two

• Negative four

What is the x value of the vertical intercept in the second graph?

• Negative two

• Zero

• Two

• Four

Does the second graph have any horizontal intercepts?

• No

• Yes, two

• Yes, three

• Yes, one

What should be entered if a graph has no horizontal intercepts?

• DNE

• Zero

• NA

• None
