Rules: (-) plus (-) equals positive.
Anything negative in absolute value will turn positive. Example, | -2 | —> 2
|-4b-8|+|-1 -b^2| +2b^3; b=-2
First step is substituting all the “b” to -2.
|-4(-2) -8| + |-1 -(-2)^2| +2(-2)^3
Then start solving.
|8-8| + |-1 -(4)| +2(-8)
|0| + |-5| -16
0 +5 -16= -11
Answer: -11
The best answer the question above is D.

Solution:
<u>Step-1: Find the slope of the line.</u>
Formula of slope: y₂ - y₁/x₂ - x₁
- y₂ - y₁/x₂ - x₁ = Slope
- => -2 - (-5)/-8 - (-4) = Slope
- => -2 + 5/-8 + 4 = Slope
- => 3/-4 = Slope
<u>Step-2: Use the point slope formula to determine the slope.</u>
Point slope form formula: y - y₁ = m(x - x₁)
- y - y₁ = m(x - x₁) = Equation of line
- => y - (-5) = -3/4{x - (-4)} = Equation of line
- => y + 5 = -3/4{x + 4} = Equation of line
- => y + 5 = -3x/4 - 3 = Equation of line
- => y = -3x/4 - 8 = Equation of line
The equation of the line is <u>y = -3x/4 - 8.</u>
