To make my inline SVG image more searchable by google, can you add alt/title properties/attributes within svg elements such as "path" "circle" "line" etc?
I already know that you can use a title tag within the "svg" tag, like this..
<svg>
<title>this is a title tag.</title>
</svg>
Below is an example of what I am talking about.
<svg version="1.1" id="Layer_1">
<style type="text/css">
.st0{fill:none;stroke:#000000;stroke-width:5;stroke-linecap:round;stroke-miterlimit:10;}
</style>
<path class="st0" title=“this is what I am talking about” d="M567,1136.2l37,10.9c13.3,3.9,27.2,3.1,39.9-2.4l0.6-0.3"/>
<line id="hi2" class="st5" alt=“This is what I am Talking About” x1="72" y1="-169.7" x2="108" y2="-169.7"/>
</svg>

As far as I am aware, alt text cannot be used on SVGs. You are right in using <title> tags, but you can also add in <desc> to add more information.

title as an attribute has no meaning in SVG, its equivalent as you point out in the question is the <title> element.
alt as an attribute also has no meaning, the SVG equivalent is the <desc> element.
