What is the definition of a y-intercept
1 answer
A y-intercept is the point where a straight line intersects the y-axis of a graph. It refers to the value of the dependent variable (usually denoted as "y") when the independent variable (usually denoted as "x") is equal to zero. In other words, it is the constant term in the equation of a line in the form "y = mx + b" (where "m" is the slope and "b" is the y-intercept). The y-intercept gives information about the initial value or starting point of the relationship between the variables.
