Answer:
[See Below]
Step-by-step explanation:
<h2>For Point Slope Form:</h2>
Point slope form is: 
'm' is the slope
(x1, y1) is a coordinate point.
<h3>Slope:</h3>
Slope is rise over run. 
We are given the points (-1,5) and (3,-3).

The slope of the line is -2.
I will use (-1,5) as the point:

<h2>For Slope Intercept:</h2>
Slope intercept is: 
'm' - Slope
'b' - y-intercept
We can use the point slope equation to convert it into slope intercept form:

<h2>For Standard Form:</h2>
Standard form is 
Using out slope intercept form equation:
