Answer: x=10
Step-by-step explanation:
x/20=14/28
28x=14 times 28
x=10
Option D:
is the equation of line in point - slope form
Explanation:
Given that the slope is
and the point 
We need to determine the equation of the line in point - slope form.
The point - slope form can be determined using the formula,

Let us substitute the point
and the slope
in the above formula.
Thus, we have,

Simplifying the terms, we get,

Thus, the equation of the line in point - slope form is 
Therefore, Option D is the correct answer.
