* The addition property says if A=B, then A+C=B+C. The substitution property further says if C=D, then A+C=B+D (D can be substituted for C). IMO, both properties are needed together to get from A=B and C=D to A+B=C+D.
Answer:
The Quadratic Formula: Given a quadratic equation in the following form:
ax2 + bx + c = 0
...where a, b, and c are the numerical coefficients of the terms of the quadratic, the value of the variable x is given by the following equation:
\small{ x = \dfrac{-b \pm \sqrt{b^2 - 4ac\phantom{\big|}}}{2a} }x=
2a
−b±
b
2
−4ac

Step-by-step explanation:
Point slope form is y-y1= m(x-x1) where m is slope and y1 and x1 are the x and y of the coordinate given.
y-1= 2(x-(-2))
y-1= 2(x+2)
Final answer: y-1= 2(x+2)
