Answer: FIRST OPTION.
Step-by-step explanation:
First, it is important to remember that the Slope-Intercept form of the equation of a line is the shown below:

Where "m" is the slope of the line and "b" is the y-intercept.
By definiton, given a System of Linear equations, if they are exactly the same line, then the System of equations have Infinely many solutions.
In this case you have the following System of Linear equations given in the exercise:

So, since you need the system has Infinite solutions, you know that the slope and the y-intercept of both lines must be equal.
Therefore, you can identify that the value of "a" and "b" must be the following:

So the Linear System would be the shown below:

The amplitude and the period of the function are 3 and 2, respectively.
<h3>What are the amplitude and the period of a sinusoidal function?</h3>
Sinusoidal functions are periodic bounded functions whose form is described below:
y = A · sin (2π · t / T + Ф) + y'
Where:
- y' - Midpoint
- A - Amplitude
- t - Time
- Ф - Phase
- T - Period
The period is the horizontal distance between two consecutive peaks or two consecutive bottoms and the amplitude is equal to the half of the distance between a peak and a consecutive bottom. Hence, the amplitude and the period are, respectively:
Amplitude
A = 0.5 · [2 - (- 4)]
A = 3
Period
T = 2 · [0.75 - (- 0.25)]
T = 2
