How can you tell if an equation of a relation represents a linear relation?
THanks to everyon who helps :)
linear = first degree only, no squares, no cubes, no square roots,no products of variable.
so x+3y=c is a linear equation
x^3+y=c is NOT
-x+12y=45 is linear
1+ xy=c is NOT
thanks so much that helped me a lot !!
