Answer:
Slope: -2/3
y = -2/3x + 3
Step-by-step explanation:
y -2 = -2/3x + 1
+2 +2
y = -2/3x +3
To plot another point, choose a point go up 2 and to the left 3 units.
Or go down 2 units and to the right 3 units.
Answer:
d. √(1/(x+1))
Step-by-step explanation:
Just as operations can be performed on numbers and variables, so can operations be performed on functions. Here, you're asked to simplify the ratio of two functions.
At this point, you're supposed to know the factoring of the difference of squares:
Answer: the slope will become negative
Step-by-step explanation: the slope becomes negative due to the negative sign and the slope line will go down left to right

Answer: the number of minutes of long distance call that one can make is lesser than or equal to 12 minutes.
Step-by-step explanation:
Let x represent the number of minutes of long distance call that one makes.
The first three minutes of a call cost $2.10. After that, each additional minute or portion of a minute of that call cost $0.45. This means that if x minutes of long distance call is made, the total cost would be
2.10 + 0.45(x - 3)
Therefore, the inequality to find the number of minutes one can call long distance for $6.15 is expressed as
2.10 + 0.45(x - 3) ≤ 6.15
2.10 + 0.45x - 1.35 ≤ 6.15
0.75 + 0.45x ≤ 6.15
0.45x ≤ 6.15 - 0.75
0.45x ≤ 5.4
x ≤ 5.4/0.45
x ≤ 12
