Which equation has a graph perpendicular to the graph 3y = 2x - 9

Answer 1

The product of slopes of perpendicular lines is -1. The slope of the given line is

m₁ = 2/3

The slope of a perpendicular line is

m₂ = -1/(2/3) = -3/2

Therefore, any line with a slope of -3/2 is perpendicular to the given line.
