I believe the answer is x=0
1 he died In 326 B.C
2 I believe the answer is 120 calories
3 the answer is -14
perp to x-3y=2 thru (2,4)
For perpendicular we swap the coefficients on x and y, negating one
3x + y = some constant
We get the constant in the obvious way from the point
3x + y = 3(2) + 4 = 6 + 4 = 10
Answer: 3x + y = 10
