Answer:
Required slope = - 6
Step-by-step explanation:
Parallel lines have same slope.
(x₁ , y₁) = (3 , -5) & (x₂ , y₂) = (1, 7)
![= \frac{7 - [-5]}{1-3}\\\\=\frac{7+5}{1-3}\\\\=\frac{12}{-2}\\\\= -6](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B7%20-%20%5B-5%5D%7D%7B1-3%7D%5C%5C%5C%5C%3D%5Cfrac%7B7%2B5%7D%7B1-3%7D%5C%5C%5C%5C%3D%5Cfrac%7B12%7D%7B-2%7D%5C%5C%5C%5C%3D%20-6)
Slope of the a line parallel to a line = -6
Jesse, to answer this, we need to see the graph. I'd help if I could! You can message me if you post it! :D

that would be your answer i believe
Answer:
B
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here the vertex = (- 2, - 3 ) , then
y = a(x - (- 2))² - 3 , that is
y = a(x + 2)² - 3
To find a, substitute any point on the graph into the equation
Using the coordinates of the y- intercept (0, 5 )
5 = a(0 + 2)² - 3 ( add 3 to both sides )
8 = a(2)² = 4a ( divide both sides by 4 )
2 = a
y = 2(x + 2)² - 3 → B
