1. Which of the following equations is in standard form (Ax + By = C)?
y = 3x - 5
2x - 4y = 8
y + 2 = 1/2(x - 3)
x/2 + y/3 = 1
2. When an equation is in standard form Ax + By = C, the coefficient A must be a integer.
3. The x-intercept of the equation 3x + 4y = 12 is .
4. Convert the equation y = -2x + 7 into standard form.
5. The slope of a line in standard form Ax + By = C is always -A/B.
