### Question Description

- True or false. The slope of a horizontal line is undefined.
- True or false. Suppose the slope of a straight line
*L*is -3/4 and*P*is a given point on*L*. If*Q*is a point on*L*lying 2 units to the right of*P*, then*Q*is situated 3/2 units below*P*. - True or false. The
*y*-intercept of the straight line with equation*Ax*+*By*+*C*= 0 is -*C*/*B*(*B*≠ 0). - True or false. If a line
*L*_{1}has equation*y*=*mx*+*b*, where*m*and*b*are constants with*m**≠*0,then an equation of a line*L*_{2}perpendicular to*L*_{1}has the form, where*C*is a constant. - True or false. Suppose an asset is being depreciated linearly. Then the rate of depreciation of the asset is given by the negative of the slope of the depreciation line.
- True or false. If
*R*and*C*are linear revenue and cost functions, respectively, and (*x*_{0},*p*_{0}) is the breakeven point, then*P*(*x*) >*P*(*x*_{0}) if*x*>*x*_{0}, where*P*is the profit function. - True or false. The least-squares line must pass through at least one of the data points.
