- 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 L1 has equation y = mx + b, where m and b are constants with m ≠ 0,then an equation of a line L2 perpendicular to L1 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 (x0, p0) is the breakeven point, then P(x) > P(x0) if x > x0, where P is the profit function.
- True or false. The least-squares line must pass through at least one of the data points.
