Graph the line that represents a proportional relationship between y and x where the unit rate of change of y with respect to x is 0.4. In other words, a change of 1 unit in a corresponds to a change of 0.4 units in y. Graph the line and write the equation of the line. y 8 6 10 8+ 7+ 9 6- 2 413 4+ 3+ 2 1- 2- 3- 2 348 00 3 4 5 6 7 8 9
