Hi!
<h3>The equation of point slope form is</h3><u>y = sx + b</u>
We need to find s and b
s = slope
b = y intercept
-------------------------------
<h3>To find the slope, use this formula. </h3>Put in the values.
The slope is 2.
<u>y = 2x + b</u>
------------------------------------
<h3>Now we need to find the y intercept. Put in a point, and solve for b. </h3>-8 = 2 * -6 + b
-8 = -12 + b
4 = b
The y intercept is 4.
<u>y = 2x + 4</u>
<h2>The answer y = 2x + 4</h2>Hope this helps! :)
