<span>standard form the equation of the line passing through the given point and having the given slope.. . C(0, 4), m = 0 </span>y-4 = 0(x-0) = 0 => y = 4 (this is a horizontal line)
First, replace all variables with the given values. 12(9) + 9(2) + 2(12) This should then equal 150, then the formula says to multiply this answer by 2. Doing so, should give a final answer of 300.
