Questions & Answers

Q: How do you find the x intercept of an equation?

To find the x intercept, set y equal to zero and solve for x. Substitute 0 for y in the equation and solve for x. This will give you the x coordinate of the point where the graph crosses the x axis.

Q: How do you find the y intercept of an equation?

To find the y intercept, set x equal to zero and solve for y. Substitute 0 for x in the equation and solve for y. This will give you the y coordinate of the point where the graph crosses the y axis.

Q: How do you determine the correct graph based on the x and y intercepts?

By finding the x and y intercepts of the equation, you can plot these points on a graph. Then, compare the given answer choices to see which one includes both the x and y intercepts obtained from the equation.

Q: Why is it important to find the intercepts of an equation?

Finding the intercepts helps determine the points on the graph of the equation. These intercepts provide crucial information about the behavior and characteristics of the equation, such as where it crosses the x and y axes.
