Understanding Intercepts and Coordinates

The video tutorial introduces the concept of x and y intercepts, explaining their significance in graphing. It demonstrates how to identify points on a graph and find x and y intercepts by setting the opposite variable to zero and solving the equation. The tutorial provides examples and step-by-step instructions to reinforce understanding.

What is the primary reason for learning about x and y intercepts?

• They are the only way to solve graph equations.

• They provide a quick and useful method for graphing.

• They are used to find the slope of a line.

• They are always the most accurate way to graph.

What is the x-coordinate of a point located at (-4, 0)?

• -4

• -1

• 0

• 4

What is the y-coordinate of a point located at (2, 0)?

• 2

• 0

• -2

• 1

What do all x-intercepts have in common regarding their y-values?

• They are all negative.

• They are all equal to x.

• They are all zero.

• They are all positive.

What is the y-coordinate of the x-intercept?

• It is always zero.

• It is always one.

• It is always equal to x.

• It is always negative.

What is the x-intercept of a graph?

• The point where the graph crosses the midpoint.

• The point where the graph crosses the origin.

• The point where the graph crosses the y-axis.

• The point where the graph crosses the x-axis.

How do you find an x-intercept on a graph?

• Set x to one and solve for y.

• Set both x and y to zero.

• Set both x and y to zero.

Where does a graph intersect the y-axis?

• At the x-intercept.

• At the origin.

• At the y-intercept.

• At the midpoint.

What is the first step in finding a y-intercept?

• Set y to one and solve for x.

• Set both x and y to zero.

• Set x to zero and solve for y.

• Set y to zero and solve for x.
