Section 5.4: Standard Form Int. Math I
Standard Form!!! Standard Form looks like this: Ax + By = C , where A and B are not both zero - Examples: (1) 1x + 4y = 5, A = B = C = (2) -3x + 5y = - 2, A = B = C = - The variables are on the left side and the constant is on the right side!!!
Example #1: Convert to Standard Form Directions: Write y = 2/5x – 3 in standard form with integer coefficients. 1. Get rid of fraction – Multiply both sides by 5 2. Distribute!!! 3. Subtract 2x from each side.
Examples #2: Write an equation in Standard Form Directions: Write in standard form an equation of the line passing through (-4,3) with a slope of -2. Use integer coefficients. 1. Use point-slope form 2. Distribute!!! 3. Add 3 to both sides 4. Add 2x to both sides
Try these!!! 1. Directions: Write y = ½ x – 4 in standard form with integer coefficients. 2. Directions: Write in standard form an equation of the line passing through (3,-5) with a slope of -3. Use integer coefficients.
