Step-by-step solution

To solve this problem, we'll follow these steps:

  • Step 1: Identify the given equation, y=4411xy = 44 - 11x.
  • Step 2: Compare it to the standard quadratic equation form, y=ax2+bx+cy = ax^2 + bx + c.
  • Step 3: Determine the values of aa, bb, and cc that make the equations equivalent.

Now, let's work through each step:
Step 1: The given equation is y=4411xy = 44 - 11x. This is a linear equation, not quadratic, because it lacks the x2x^2 term.
Step 2: The standard form for a quadratic equation is y=ax2+bx+cy = ax^2 + bx + c. In our case, since there is no x2x^2 term, we can deduce a=0a = 0.
Step 3: Compare terms. The equation can be rewritten as y=0x211x+44y = 0 \cdot x^2 - 11x + 44. By comparing both sides with ax2+bx+cax^2 + bx + c, we find:

  • a=0a = 0 since there is no x2x^2 term.
  • b=11b = -11 which is the coefficient of xx.
  • c=44c = 44, which is the constant term.

Therefore, the parameters are a=0\mathbf{a = 0}, b=11\mathbf{b = -11}, c=44\mathbf{c = 44}, matching choice 2.
