The y-intercept of a line is the point where the line crosses the y-axis on a graph. In simpler terms, it’s the value of y at the moment when the x-coordinate is zero. This point helps to show where the line starts vertically on the graph and is often used in equations to understand the relationship between x and y. For instance, if you have a line represented by an equation, the y-intercept indicates what happens to the value of y when there is no contribution from x.
Describe what y intercept of a line is in your own words.
