What Is a Direct Relationship Graph?
A direct relationship graph is a graph where one variable either increases or decreases along with the other. The general equation for a direct relationship graph is y = mx + b, where “y” denotes the dependent variable, “x” indicates the independent variable, “m” represents the slope of the line and “b” is the y-intercept.
A graph is a useful tool in mathematics. It is a visual representation showing different correlations between variables or parameters of a given function. In a direct relationship graph, the value on the y-axis varies at the same rate and direction as the values on the x-axis. The opposite of a direct relation graph is an inverse relationship graph.
