Understanding Y Intercept: Definition and Importance in Math
What is the definition of y-intercept?
The y-intercept is the point where a line crosses the y-axis. It is the value of y when x=0.
Why is the y-intercept important?
The y-intercept is important because it provides information about the starting point or initial value of a linear equation. It can also be used to determine the slope of the line.
How is the y-intercept calculated?
The y-intercept can be calculated by substituting zero for x in the equation of the line and solving for y.
What does a negative y-intercept mean?
A negative y-intercept means that the line crosses the y-axis below the origin. It indicates that the initial value or starting point of the equation is less than zero.
What does a y-intercept of zero mean?
A y-intercept of zero means that the line crosses the y-axis at the origin, where x and y are both zero.
