Answer:
<h2>2x + 5y = -15</h2>
Step-by-step explanation:
The standard form of an equation of a line:

We have the equation in point-slope form:

Convert it to the standard form:
<em>multiply both sides by 5</em>
<em>use the distributive property </em><em>a(b + c) = ab + ac</em>

<em>subtract 35 from both sides</em>
<em>add 2x to both sides</em>

the answer to 300000 THAT'S THE ANSWER
