Answer: The required system of equations representing the given situation is
Step-by-step explanation: Given that Sam needs to make a long-distance call from a pay phone.
We are to write a system to represent the situation.
Let x represent the number of minutes Sam talked on the phone and y represents the total amount that he paid for the call.
According to the given information,
with prepaid phone card, Sam will be charged $1.00 to connect and $0.50 per minute.
So, the equation representing this situation is
Also, if Sam places a collect call with the operator he will be charged $3.00 to connect and $0.25 per minute.
So, the equation representing this situation is
Thus, the required system of equations representing the given situation is

Answer:
On a coordinate plane, a dashed straight line has a positive slope and goes through (negative 4, 2) and (4, 4). Everything below and to the right of the line is shaded.
Step-by-step explanation:
The first step is writing in the general form of the first order equation
y = f(x) or y > f(x) or y < f(x)
And
f(x) = ax + b
In which a is the slope.
We have that:
x - 2y > -6
-2y > -6 - x
When multiplying by -1, the signal changes, from > to <
2y < x + 6
y < 0.5x + 3
The slope is positive, since 0.5 is positive.
Since it is y lesser than, it is everything below and to the right of f(x) is painted.
The line is dashed because this is just lesser, not lesser or equal.
The correct answer is:
On a coordinate plane, a dashed straight line has a positive slope and goes through (negative 4, 2) and (4, 4). Everything below and to the right of the line is shaded.
