x equals y
Transitive property: If 8 equals x and x equals y, then 8 equals y.
Type your answer here... y = -x -3
If [ y = x + 2 ], then x is not -1 when y = 5.If [ y = x + 2 ],then when x = -1, y = 1,and when y = 5, x = 3.
x equals -12 and y equals 1/4 of -12, so y = -3.
Y varies in direct proportion to x.
y - |x| is an expression, not a function.
It depends on how y depends on x.
