Converting Linear Equations to Standard Form

This video tutorial explains how to convert linear equations into standard form. It begins by defining the standard form of a line as Ax + By = C, where A, B, and C are integers. The tutorial then demonstrates the conversion process using two example equations: y = 3x + 1 and y = 1/2x - 3. For the first equation, the process involves rearranging terms to get x and y on the same side. For the second equation, additional steps are needed to eliminate the fractional coefficient by multiplying through by the denominator. The video emphasizes the importance of having integer coefficients in the final standard form.

What is the main topic of the video?

• Solving quadratic equations

• Converting equations to standard form

• Graphing linear equations

• Finding the slope of a line

What is the general form of a line?

• y = mx + b

• ax^2 + bx + c = 0

• ax + by = c

• x^2 + y^2 = r^2

What must the coefficients A, B, and C be in the general form of a line?

• Fractions

• Decimals

• Integers

• Variables

In the equation y = 3x + 1, what is the first step to convert it to standard form?

• Add 3x to both sides

• Subtract 3x from both sides

• Divide both sides by 3

• Multiply both sides by 3

After subtracting 3x from both sides in the equation y = 3x + 1, what is the resulting equation?

• 3x + y = 1

• y - 3x = 1

• -3x + y = 1

• y = -3x + 1

Why is it conventional to have the A term positive in the standard form?

• It makes the equation easier to solve

• It simplifies the graphing process

• It is a mathematical rule

• It is a common convention

What is the challenge in converting the equation y = 1/2x - 3 to standard form?

• The coefficient of y is zero

• The coefficient of x is a fraction

• The constant term is negative

• The equation is already in standard form

What should you multiply both sides by to eliminate the fraction in the equation y = 1/2x - 3?

• 2

• 1

• 1/2

• 3

After multiplying both sides by 2 in the equation y = 1/2x - 3, what is the resulting equation?

• 2y = 2x - 6

• 2y = x - 6

• 2y = 1/2x - 6

• y = x - 6

What is the final standard form of the equation y = 1/2x - 3 after all transformations?

• x + 2y = -6

• 2x - y = 6

• x - y = 6

• x - 2y = 6
