Finding Values on Graphs

The video tutorial guides viewers through the process of finding corresponding y-values for given x-values on a graph and vice versa. It starts with finding y when x is -4, then moves to finding y when x is 3. The strategy shifts to finding x when y is -2, followed by finding x when y is 0. The tutorial concludes with finding y when x is 8, emphasizing the importance of understanding the relationship between x and y on a graph.

What is the y-value when x is -4 on the graph?

• 7

• 6

• 8

• 5

When x is -4, which of the following is true about the y-value?

• It is less than 6

• It is exactly 6

• It is more than 8

• It is between 6 and 8

What is the first step in finding y when x is a specific value?

• Locate y on the y-axis

• Locate y on the x-axis

• Locate x on the x-axis

• Locate x on the y-axis

What is the y-value when x is 3 on the graph?

• 2

• 1

• 0

• -1

When x equals 3, what is the position of the graph relative to the x-axis?

• Below the x-axis

• Not touching the x-axis

• On the x-axis

• Above the x-axis

What is the significance of the point where the graph crosses the x-axis?

• y is positive

• y is negative

• y is zero

• y is undefined

What is the y-value when x is 3 and the graph crosses the x-axis?

• -1

• 2

• 0

• 1

What is the x-value when y is -2 on the graph?

• 4

• 6

• 3

• 5

When y equals -2, which x-value corresponds to it on the graph?

• 4

• 3

• 5

• 2

What strategy is used to find x when y equals -2?

• Check the slope

• Check the origin

• Check the y-axis

• Check the x-axis
