Understanding Intercepts in Graphs

The video tutorial explains how to determine the x-intercept and y-intercept of lines on a graph. It covers several examples, including lines that intersect the axes at different points, a horizontal line with no x-intercept, and a line passing through the origin. The tutorial emphasizes understanding the coordinates of intercepts and how to identify them on a graph.

What is the x-intercept of the first graph?

• (5, 0)

• (0, 5)

• (-5, 0)

• (0, -5)

Which of the following is true about any point on the x-axis?

• It has both coordinates as zero.

• It has a y-coordinate of five.

• It has a y-coordinate of zero.

• It has an x-coordinate of zero.

What is the y-intercept of the first graph?

• (0, 5)

• (5, 0)

• (0, -5)

• (-5, 0)

What is the x-intercept of the second graph?

• (4, 0)

• (0, 4)

• (0, -4)

• (-4, 0)

What is the y-intercept of the second graph?

• (0, -100)

• (0, 100)

• (-100, 0)

• (100, 0)

What should you enter if there is no intercept in the homework system?

• None

• NA

• Zero

• DNE

What is the y-intercept of the horizontal line example?

• (0, 20)

• (-20, 0)

• (20, 0)

• (0, -20)

What is the x-intercept of a line passing through the origin?

• (1, 0)

• (0, 0)

• (1, 1)

• (0, 1)

What is the y-intercept of a line passing through the origin?

• (1, 1)

• (0, 0)

• (1, 0)

• (0, 1)

Which point is on both the x-axis and y-axis?

• (1, 0)

• (1, 1)

• (0, 0)

• (0, 1)
