Answer:
D. Factor out 3 from the first two terms.
Step-by-step explanation:
Vertex form is ...
y = a(x -h)² +k
where (h, k) is the vertex and "a" is the vertical scale factor.
This equation expands to give ...
y = ax² -2ahx + ah² +k
Factoring "a" from the terms involving x makes it easy to identify h and so finish putting the equation into vertex form. In this equation, that means the most appropriate first step is ...
factor out 3 from the first two terms
The equation would be y = -5/2x - 14. Since the slope and a coordinate pair was given, I used point slope form to figure out the equation.
Work:
y - 6 = -5/2 (x+8)
y - 6 = -5/2x - 20
+ 6 +6
______________
y = -5/2x - 14
Answer: 4m+-24n+3
This could be or you can write it like 4m-24n+3. And that’s the answer depends on what your doing. And you can’t simply anymore so that’s the best answer.
