Q. Determine the standard form of the following equation:y=7x+4
Rearrange equation for standard form: To rewrite the equation y=7x+4 in standard form, we need to rearrange the terms so that the x and y terms are on one side of the equation and the constant is on the other side. We want it in the form Ax+By=C.
Subtract x term from both sides: The given equation is y=7x+4. To get it into standard form, we need to subtract 7x from both sides of the equation to move the x term to the left side.
Adjust x coefficient to be positive: Subtracting 7x from both sides gives us −7x+y=4. This is almost in standard form, but we typically want the x coefficient to be positive.
Multiply equation by −1: To make the x coefficient positive, we can multiply the entire equation by −1. This gives us 7x−y=−4.
Check coefficients for GCF: Now the equation is in standard form, Ax+By=C, with A=7, B=−1, and C=−4. We need to check that A, B, and C are integers whose greatest common factor (GCF) is 1.
Verify standard form : The GCF of 7, −1, and −4 is indeed 1, so the equation is in standard form where A and B are not both zero, and A, B, and C are integers whose GCF is 1. .
