<h2>'
' in the form of
- b.</h2>
Step-by-step explanation:
We have,
+ 8x + 15
To express
+ 8x + 15 in the form of
- b = ?
∴
+ 8x + 15
Adding and subtracting 1, we get
=
+ 8x + 15 + 1 - 1
=
+ 8x + 16 - 1
=
+ 2(x)(4) +
- 1
Using the algebraic identity,

= 
Thus,
in the form of
- b.
Answer:
Step-by-step explanation:
I'm pretty sure that the equation for slope is y2 -y1
-----------
x2 - x1
Substitute in the info, and simplify to find the slope.
1. 1x-11. 6x+9 + 5x-20 = 1x-11
2. -2x-11. X-8 -3x-3 = -2x-11
