Answer:

Vertex is (-1, -9)

Step-by-step explanation:

To find the x-value of the vertex, we use the formula

x

=

−

b

2

a

(This is considered the axis of symmetry).

a

=

1

and

b

=

2

with

c

=

−

8

(These are the numbers in order)

By substituting we get

x

=

−

(

2

)

2

⋅

1

, which simplifies to

x

=

−

1

.

Once you find x, substitute back into the equation to find y.

y

=

(

−

1

)

2

+

2

(

−

1

)

−

8

y

=

1

−

2

−

8

y

=

−

9

Putting the two numbers together you get the coordinates

(

−

1

,

−

9

)

.

Given:

The points are M(6,16) and Z(-1,14).

To find:

The distance between given points.

Solution:

Distance formula:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

So, the distance between two points M(6,16) and Z(-1,14) is

d=\sqrt{(-1-6)^2+(14-16)^2}

d=\sqrt{(-7)^2+(-2)^2}

d=\sqrt{49+4}

d=\sqrt{53}

d=7.28011

d\approx 7.3

Therefore, the distance between given points is 7.3 units.
