Which choice is the equation of a line that passes through point (7, 3) and is parallel to the line represented by this equation?y=2/7x-3 A. 7x + 3y = 2 B. y=2/7x+1 C. y=-7/2x-3 D. 2x + 7y = 1
Weegy: A. 7x + 3y = 2 User: Which choice could be the equation of a line perpendicular to the line represented by this equation? y = 5 A. y = 4x- 9 B. y=-1/5x C. y = 5x D. x = 5 Weegy: y = 5 This is an equation of a horizontal line that crosses the y-axis at (0, 5) A perpendicular line would be a vertical line, whose equation looks like x = #, D is the only one that fits the case User: Which choice is the equation of a line that has a y-intercept of –3 and is perpendicular to the line represented by this equation? y=2/3x+1 A. B. y = 3x- 3 C. y=-3/2x-3 D. y=3/2x+3 (More)
