Definition: In mathematics, a connection is a mathematical concept that describes how two objects are related or connected. It can be used to represent relationships between variables in equations and expressions. For example, if we have an equation such as y = 2x + 3, then the x-intercept of this line represents the point where the value of y equals zero. This means that when x is zero, y must equal zero, so there is no solution to the equation for any values of x. In
