Exploring X and Y Intercepts

The video tutorial by Mystique covers the concepts of x and y intercepts, explaining their definitions and how to identify them from graphs, tables, and equations. The tutorial emphasizes the importance of understanding both intercepts, although the focus is on y-intercepts for seventh-grade assignments. The video also provides instructions for a foldable activity to reinforce learning.

What is the definition of an x-intercept?

• The x value where the graph crosses the x-axis

• The y value where the graph crosses the x-axis

• The x value where the graph crosses the y-axis

• The y value where the graph crosses the y-axis

In the ordered pair for an x-intercept, what is always the value of y?

• 1

• x

• y

• 0

How do you identify the x-intercept from a graph?

• Find where the line crosses the y-axis

• Find where the line is horizontal

• Find where the line crosses the x-axis

• Find where the line touches the origin

What is the x-intercept of a graph if the line crosses the x-axis at -4?

• (0, -4)

• (0, 4)

• (-4, 0)

• (4, 0)

How do you identify the y-intercept from a graph?

• Find where the line touches the origin

• Find where the line is vertical

• Find where the line crosses the x-axis

• Find where the line crosses the y-axis

What is the y-intercept of a graph if the line crosses the y-axis at 2?

• (0, 2)

• (2, 0)

• (-2, 0)

• (0, -2)

How do you find the x-intercept from a table?

• Look for the row where x is maximum

• Look for the row where x and y are equal

• Look for the row where y is zero

• Look for the row where x is zero

What is the x-intercept if y is zero and x is 6 in a table?

• (0, -6)

• (-6, 0)

• (6, 0)

• (0, 6)

How do you calculate the x-intercept from an equation?

• Set both x and y to zero

• Set x to one and solve for y

• Set y to zero and solve for x

• Set x to zero and solve for y

What is the y-intercept of the equation y = 1/4x - 1?

• -1

• 0

• 1/4

• 1
