Q. What is y=56x+9 written in standard form?Choose 1 answer:(A) −6x+y=45(B) −6x+5y=9(C) −6x+y=9(D) −6x+5y=45
Multiply by 5: To convert the equation y=56x+9 into standard form, we need to rearrange it so that it is in the form Ax+By=C, where A, B, and C are integers, and A should be non-negative.First, we multiply both sides of the equation by 5 to eliminate the fraction.5⋅y=5⋅(56x+9)
Combine like terms: After multiplying, we get:5y=6x+45Now we need to move the term with x to the same side as the y term to get the equation in standard form.
Move x term to left side: Subtract 6x from both sides of the equation to move the x term to the left side:5y−6x=45
Rearrange terms: The standard form of a linear equation is Ax+By=C. To match this form, we need to rearrange the terms so that the x term comes before the y term:−6x+5y=45
Compare to answer choices: Now the equation is in standard form. We can compare it to the answer choices given:(A) −6x+y=45(B) −6x+5y=9(C) −6x+y=9(D) −6x+5y=45
