Q. What is y=56x+9 written in standard form?Choose 1 answer:(A) −6x+y=9(B) −6x+5y=9(C) −6x+y=45(D) −6x+5y=45
Multiply by 5: First, we multiply both sides of the equation by 5 to eliminate the fraction.5(y)=5(56x+9)This simplifies to:5y=6x+45
Move term : Next, we move the term 666x to the left side of the equation to have all terms on one side.\newline−6-6−6x + 555y = 454545
Check answer choices: Now, we check the answer choices to see which one matches our equation.\newline(A) −6x+y=9-6x + y = 9−6x+y=9 (This is not correct because the coefficient of yyy is not 555 and the constant term is not 454545.)\newline(B) −6x+5y=9-6x + 5y = 9−6x+5y=9 (This is not correct because the constant term is not 454545.)\newline(C) −6x+y=45-6x + y = 45−6x+y=45 (This is not correct because the coefficient of yyy is not 555.)\newline(D) −6x+5y=45-6x + 5y = 45−6x+5y=45 (This is correct because it matches the equation we derived.)
