Explanation:

Part A.

1. You have provided an estimate of 600 minutes per month.

__

2. The cheapest plan is likely to be Plan 6 (Public Mobile), as it has no per-minute charge.

__

Part B.

1. Table 2.

See the first attachment for Table 2. For the chosen plan, there is no per-minute charge, so the monthly charge is the same for all numbers of minutes.

__

2. Rate of Change and Slope (m)

a) Adding a minute adds $0 to the cost

b) The rate of change (m) is 0/1 = 0 (dollars per minute)

__

3. Initial value (b)

a) The plan costs $24.00 when no minutes are used.

b) The initial value (b) is 24.

__

4. Equation of the line

a) Filling the found values of m and b into the equation of the line, we have ...

  y = mx + b

  y = 0x + 24

  y = 24 . . . . . . simplified

__

Part C.

Table 3 can be found in the second attachment.

The b in each case is the value from the Monthly Cost column of Table 1.

The m in each case is the value from the Cost per minute column of Table 1.

The equation is found by copying the values of m and b into y = mx + b.

The number in the last column is found by multiplying the minutes (x) by m, then adding b. For example, your cost for Plan 5 (BELL) is ...

  y = 0.10x + 10

  y = (0.10)(600) +10 = 60 +10 = 70
