Gradient of given line is 2.1/5 = 21/50 So gradient (slope) of perpendicular is -50/21 = -2.381 (to 3 dp)
perpendicular to y = 2x + 3, y-intercept is 5.the answer is y = -½x + 5if you are still confused, i want you to follow the link below. it's a math help vedio that explain the concept clearly.http://www.brightstorm.com/d/math/s/algebra/u/linear-equations-and-their-graphs/t/writing-equations-in-slope-intercept-form
The correct set of coefficient for an equation depends with the equation in question. There are many types of equations.
The answer is given below.

you didn't put any equations, but the answer probably begins with y= (x-4)^2+1
No solution
Just one.
10^a=300.. apex!
c=3^27

It might have been possible to answer the question if you had bothered to include any equations below. But since you haven't there can be no answer.
