ALG: 12-1 (Writing inv. variation equations)

Write the inverse variation in which x = 5 and y = 11. y = x y = x y = x Answer not shown Write the inverse variation in which x = -10 and y = 2. y = x y = x y = 20 Answer not shown If xy = 50, what is the equation written in inverse variation form? y = 5 xy = 50 y = 50 Answer not shown Write the inverse variation in which x = -8 and y = -7. y = x y = x y = - x Answer not shown If the equation of an inverse variation is y= x (-3, 5) (15, -1) (2, 7.5) (10, 5) If the equation of an inverse variation is y= x NOT be on the graph? (-4, 5) (10, -2) (1, -20) (4, 5) Is the equation an inverse variation? y = 5x + 2 Yes No Is the equation an inverse variation? y = -16x ^{2} + 2x-6Yes No Is the equation an inverse variation? y = x Yes No Is the equation an inverse variation? xy = 9 Yes No Is the equation an inverse variation? x = y Yes No |
