Select all statements that are true of regression lines. The units of all regression variables must be the same. In regression, the variable being predicted is the explanatory variable. Least squares regression is not the only form of regression analysis. Regression lines describe how one variable changes as the other variable changes. The predicted value from a regression equation is always meaningful.

Determine the standard form of the equation of the line that passes through (-2,0) and (8,-5)
