Answer:
A. 
Step-by-step explanation:
We have been given an equation of a line in point-slope form. We are asked to write our given equation in standard form.

Since we know that standard form of equation is:
, where, a, b and c are constants.
Let us multiply both sides of our given equation by 2.


Let us add 6 to both sides of our equation.


Let us subtract x from both sides of our equation.


Multiply both sides of our equation by -1.

Rearranging our equation we will get,

Therefore, the standard form of our given equation is
and option A is the correct choice.

Answer:
12.9
Step-by-step explanation:
sin 59 = opposite/hypotenuse
opposite is x, the dimension facing the angle 59
hypotenuse is the longest side = 15
sin 59 = x/15
x = 15sin59 = 15 x 0.8572 =12.858 = 12.9 in the nearest tenth
