Q. What is y=−31x−9 written in standard form?Choose 1 answer:(A) x+3y=−27B y=−31(x+27)(C) 3y=−x−27(D) 31x+y+9=0
Step 1: Multiply by 3: To write the equation y=−31x−9 in standard form, we need to get the x and y terms on one side of the equation and the constant term on the other side. The standard form of a linear equation is Ax+By=C, where A, B, and C are integers, and A should be non-negative.
Step 2: Move x term: First, we multiply every term by 3 to eliminate the fraction. This gives us 3y=−x−27.
Step 3: Check standard form: Next, we move the x term to the left side of the equation by adding x to both sides. This results in x+3y=−27.
Step 3: Check standard form: Next, we move the x term to the left side of the equation by adding x to both sides. This results in x+3y=−27.Now, we check if the equation x+3y=−27 is in standard form. The coefficients are integers, and the x coefficient is positive, so the equation is in standard form.
