For the first representation, the equation is : y = 3x-5.
For the second representation, the equation is : y = -12x+2.
For the third representation, the equation is : y = 5/4x-5.
For the fourth representation, the equation is: y = -6x+3.
Analyze the representations given in the question, in order to find its corresponding equation.
According to the question,
For the first representation, y=1 when x=2, y=-2 when x=1 and y=4 when x=3. On substituting these values of x and y in the given equations, we get that y = 3x-5.
Similarly, for the second representation, we get, y = -12x+2.
For the third representation, we get, y = 5/4x-5.
For the fourth representation, we get, y = -6x+3.
