How to determine the y intercept of a quadratic equation

The video tutorial explains how to find the Y intercept of a graph. It emphasizes that the Y intercept occurs when the X value is zero. The tutorial covers different forms of equations, including standard form, and highlights that the Y intercept is the constant term in the equation. The instructor advises checking calculations and understanding the concept thoroughly.

What is the value of X when finding the Y-intercept?

• 2

• 1

• 0

• -1

In which form is it straightforward to find the Y-intercept?

• Slope-intercept form

• Quadratic form

• Standard form

• Point-slope form

What should you do if the equation is not in standard form?

• Guess the Y-intercept

• Use a calculator

• Ignore the Y-intercept

• Convert it to standard form

What is the Y-intercept in the equation Y = C when X is zero?

• C

• -1

• X

• 0

Why is it important to double-check your work when finding the Y-intercept?

• To save time

• To impress the teacher

• To ensure accuracy

• To avoid using a calculator
