E)y = - 380x

Quizplus · Accepted Answer

Since y is directly proportional to x, the relationship can be described by the equation y = kx, where k is the constant of proportionality. Given x = 5 and y = 380, we can find k by substituting these values into the equation: 380 = k(5), which gives k = 76. Therefore, the linear model is y = 76x.
