Answer:
110
Step-by-step explanation:
Y and X have to equal 180
70+x+180
=110
The point-slope form:

We have the points (3, -4) and (5, 1). Substitute:

The standard form: 
<em>multiply both sides by 2</em>
<em>use distributive property</em>
<em>subtract 2y from both sides</em>
<em>subtract 15 from both sides</em>

<h3>Answer: 5x - 2y = -7</h3>
