Finding Intercepts of an Equation

The video tutorial explains how to find the intercepts of an equation. It begins with an introduction to intercepts, defining x and y intercepts. The x-intercept is where the graph crosses the x-axis, meaning y is zero, while the y-intercept is where the graph crosses the y-axis, meaning x is zero. The tutorial then provides step-by-step instructions to calculate the x-intercept by setting y to zero in the equation and solving for x. Similarly, it demonstrates finding the y-intercept by setting x to zero and solving for y. The video concludes by showing how these intercepts can be used to graph the equation.

What are the two types of intercepts discussed in the video?

• X-intercept and Y-intercept

• Y-intercept and Z-intercept

• X-intercept and Z-intercept

• Z-intercept and W-intercept

What is the value of y at the x-intercept?

• None of the above

• 1

• 0

• Depends on the equation

When finding the x-intercept, what value is substituted for y in the equation?

• Any negative number

• Any positive number
