# Finite Math True or False

**Question description**

If you think the statement is true, then prove it. On the other hand, if you think the statement is false, then give an example that disproves the statement. For example, the statement "If

aandbare real numbers, thena-b=b-a" is false and an example that disproves it may be constructed by takinga= 3 andb= 5. For these values ofaandb, we finda-b= 3 - 5 = -2 butb-a= 5 - 3 = 2 and this shows thata-b≠b-a. Such an example is called a ≠counterexample.

- True or false. The slope of a horizontal line is undefined.
- True or false. Suppose the slope of a straight line
Lis -3/4 andPis a given point onL. IfQis a point onLlying 2 units to the right ofP, thenQis situated 3/2 units belowP.- True or false. The
y-intercept of the straight line with equationAx+By+C= 0 is -C/B(B≠ 0).- True or false. If a line
L_{1}has equationy=mx+b, wheremandbare constants withm≠0,then an equation of a lineL_{2}perpendicular toL_{1}has the form [img width="94" height="41" alt="" src="https://angel.grantham.edu/AngelUploads/Content/MA17020142727425/_assoc/D95007AF90CF43F7A16F640D32B1B587/equation.png"> , whereCis 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
RandCare linear revenue and cost functions, respectively, and (x_{0},p_{0}) is the breakeven point, thenP(x) >P(x_{0}) ifx>x_{0}, wherePis the profit function.- True or false. The least-squares line must pass through at least one of the data points.
