Answer:

$B(-7,-4)$

Step-by-step explanation:

Let the co-ordinates of B be $(x_{2},y_{2})$

If a point $M(x,y)$ is a mid-point of line segment AB with $A(x_{1},y_{1})$ and $B(x_{2},y_{2})$ , then:

$x=\frac{x_{1}+x_{2}}{2}\\y=\frac{y_{1}+y_{2}}{2}$

Here, $M(x,y)$ is $M(-4,-3), A(x_{1},y_{1})$ is $A(-1,-2)$ .

So, $x = -4, y = -3, x_{1} = -1, y_{1}=-2$

Plug in the formula and solve for unknowns.

$x=\frac{x_{1}+x_{2}}{2}\\-4=\frac{-1+x_{2}}{2}\\x_{2}=-8+1=-7\\\\y=\frac{y_{1}+y_{2}}{2}\\-3=\frac{-2+y_{2}}{2}\\y_{2}=-6+2=-4$

Therefore, the co-ordinates of point B are $B(-7,-4)$

Answer: A (3, -4)

Step-by-step explanation:

A minimum is at the lowest point on the parabola. The minimum and maximum can be seen by looking at the vertex.

If you go right 3 spaces on the x-axis horizontally, then down 4 spaces vertically on the y-axis you get (3, -4).

4 is negative because you are going down below the x-axis.
