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! :)

Step-by-step explanation:
I just did your welcome have fun
Base is 11 cm
Height is 8 cm
A+b=4
a-b=8
2a=12
a=6
b=4-6=-2
