Graph the line using the slope and y-intercept, or two points.
Slope= -5
y- intercept= (0,2)
The answer has two points (0,2) and (1,-3) place them and then make a line going left through them.
For any equation,

assume solution of a form, 
Which leads to,

Simplify to,

Then find solutions,

For non repeated real root y, we have a form of,

Following up,
For two non repeated complex roots
where,

and,
the general solution has a form of,

Or in this case,

Now we just refine and get,

Hope this helps.
