Question

I need both the answers and the explanation, please see the entire question.

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 a and b are real numbers, then a - b = b - a" is false and an example that disproves it may be constructed by taking a = 3 and b = 5. For these values of a and b, we find a - b = 3 - 5 = -2 but b - a = 5 - 3 = 2 and this shows that a - b ? b - a. Such an example is called a &#8800counterexample.

Explanation / Answer

1. FALSE

the slope of a horizantal line is zero

2.TRUE when a triangle is formed there x=2(givem;slope = y/x)=-3/4 ==>> y= - 3/2 ie.>> 3/2 downwards

3.TRUE y= - (A/B)x - (C/B)

4.L2: y = - (1/m)*x + C

5.FALSE since we have already said "rate of depreciation(decreasing)",then no need of negative sign

6.TRUE after break even point, profit increases as x increases

7.FALSE; the least-squares best fit line is not required to pass through any of the data points. It might pass through some of them, or it might pass through none of them.
