Question 1080443
<pre>
You have a point and a slope given, so what you need is 
the point-slope formula:

{{{y-y[1]}}}{{{""=""}}}{{{m(x-x[1])}}}

In place of y<sub>1</sub>, substitute 4, 
In place of m, substitute 4 
In place of x<sub>1</sub>, substitute (-6), 
Don't substitute anything for y or x.  Leave them as x and y

Then simplify to the form {{{y}}}{{{""=""}}}{{{mx+b}}}.
