Q. What is y=45x+2 y=\frac{4}{5} x+2 written in standard form?\newlineChoose 11 answer:\newline(A) y=45(x+52) y=\frac{4}{5}\left(x+\frac{5}{2}\right) \newline(B) 4x+5y=10 -4 x+5 y=10 \newline(C) 45x+y2=0 -\frac{4}{5} x+y-2=0 \newline(D) 5y=4x+10 5 y=4 x+10
  1. Understanding the goal: Understand the goal.\newlineWe need to rewrite the equation y=45x+2y=\frac{4}{5}x+2 in standard form. The standard form of a linear equation is Ax+By=CAx + By = C, where AA, BB, and CC are integers, and AA should be non-negative.
  2. Eliminating the fraction: Multiply both sides of the equation by 55 to eliminate the fraction.\newline5y=5×(45x+2)5y = 5 \times \left(\frac{4}{5}x + 2\right)\newline5y=4x+105y = 4x + 10
  3. Moving the xx term: Move the term with xx to the left side of the equation to get terms with variables on one side and constants on the other.\newline5y4x=105y - 4x = 10
  4. Rearranging to standard form: Rearrange the terms to match the standard form Ax+By=CAx + By = C.\newline4x+5y=10-4x + 5y = 10
  5. Checking the coefficient of x: Check if the coefficient of x is non-negative. If it is negative, we can multiply the entire equation by 1-1 to make it non-negative. However, this is not strictly necessary as some definitions of standard form allow for a negative A.
  6. Verifying standard form and coefficients: Verify that the equation is in standard form and that all the coefficients are integers.\newlineThe equation 4x+5y=10-4x + 5y = 10 is in standard form, and all coefficients are integers.
