To compare the initial values of Linear Function 1 and Linear Function 2, let's look at each of them:
-
Linear Function 1: Lionel’s cell phone plan costs $45 per month. This means the cost starts at $45 when no months have passed, so the initial value is: \[ \text{Initial Value (Function 1)} = 45 \]
-
Linear Function 2: The relationship between the number of months Ruby has had her cell phone (x) and the total cost (y) is given by the equation: \[ y = 40x + 60 \] In this linear function, the initial value is the value of \(y\) when \(x = 0\): \[ \text{Initial Value (Function 2)} = 40(0) + 60 = 60 \]
Now, comparing the initial values:
- Initial Value of Linear Function 1: $45
- Initial Value of Linear Function 2: $60
Thus, we find that Linear Function 1 has the lesser initial value.
The correct response is: Linear Function 1 has the lesser initial value, with an initial value equal to $45 while Linear Function 2 has an initial value equal to $60.
