WebThe gradients of parallel lines are equal. Perpendicular lines are lines that cross at 90^o 90o to each other. The gradients of perpendicular lines multiply together to make -1 −1 (they are negative reciprocals of each other). Example: Show that the two lines y = 6 - 4x y = 6 − 4x and 4y = x 4y = x are perpendicular. WebAt the three stations, benthic invertebrates were collected by scraping 20 × 20 cm surface (4 replicates × station × years: 8 replicates per station in total); ... A similar pattern is observed for the number of species showing significant differences along the gradient in both years (ANOVA K–W: H = 6.42; p < 0.05 for 2016, K–W: ...
