If you take a look at each group of coefficients [2x and 5y, 4x and 10y], they have a proportionalrelationship,so when converting from <em>Linear Standard Form</em> to <em>Slope-Intercept</em><em> </em><em>Form</em>,<em> </em>they will always have an exact same <em>rate</em><em> </em><em>of</em><em> </em><em>change</em><em> </em>[<em>slope</em>] of −⅖.
