y+=+mx%2Bb

-1+=+%284%29%28-1%29%2Bb

-1+=+-4%2Bb

-1%2B4+=+b

3+=+b

b+=+3

So the equation of the line is y+=+4x%2B3

The slope intercept form is:
+y+=+m%2Ax+%2B+b+
+m+ = slope
+b+ = y-intercept
------------------
given:
The line passes through (-1,-1)
The format is (x,y), so I can say
+-1+=+m%2A%28-1%29+%2B+b+
Also given is +m+=+4+
+-1+=+4%2A%28-1%29+%2B+b+
+b+=+1%2F4+
So, the equation is
+y+=+4x+%2B+1%2F4+
Here's a plot of this line:
