That is a right triangle.  That means that the other 2 angles added together equal 90, because a right angle measures 90 degrees and all the angles added together in a triangle equal 180.  So the first equation is x + y = 180.  If y is 15 less twice x, then 2x - 15 = y, or 2x - y = 15, if we are solving it for 15 and putting it into standard form of a line.  What you are looking for is the third choice down.

Answer:

y = x - 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 1, thus

y = x + c ← is the partial equation

To find c substitute (5, 3) into the partial equation

3 = 5 + c ⇒ c = 3 - 5 = - 2

y = x - 2 ← equation of line
