A diagonal line is a line segment joining two nonconsecutive vertices of a polygon. if you mean that every sloping line,then all lines could be considered diagonal
number is 3.8
subtract 4 from -15 then divide by five
If it's a rhombus, then the diagonals are equal.
The common denominator is (x+2)(x-2)
notice that x²-4 is the difference of two square
when you solve it you get (x+2)(x-2). (x+2) can go into (x+2)(x-2).
The answer is y=-3. hope it helps
