- Q1Which of the following represents a line with a negative slope?y = -2x + 3y = -3x + 5y = 4x + 2y = 2x + 4y = 3x - 130s
- Q2Which of the following equations represents a line that passes through the points (1, 4) and (-2, 7)?y = -1x + 3y = 2x - 5y = 3x + 1y = -2x + 6y = -3x - 230s
- Q3Which of the following represents a perpendicular line to the equation y = -3x + 2?y = 3x + 2y = -3x - 1y = -1/3x + 4y = -3x + 8y = 1/3x + 430s
- Q4Which of the following represents a parallel line to the equation y = 2x + 3?y = 3x + 2y = -2x - 1y = -2x + 3y = 2x + 5y = 2x - 130s
- Q5What is the point-slope form of the equation of a line passing through the point (4, 2) with a slope of -3?y - 2 = -3(x - 4)y - 2 = -3x + 4y = -3(x + 4)y - 4 = -3(x - 2)y = -3x + 230s
