# Find the distance between (-8, -2)and 6, -1)

The distance between the given coordinate points is units.

The given coordinate points are (-8, -2) and (6, -1).

The distance formula which is used to find the distance between two points in a two-dimensional plane is also known as the Euclidean distance formula. On plane the distance between two points and is Distance .

Substitute and in distance formula, we get

Determine the axis of symmetry, x =

Step-by-step explanation:

And we want to determine its axis of symmetry.

Notice that this is in vertex form:

Where (h, k) is the vertex of the parabola.

From our function, we can see that h = 4 and k = -2.5. Hence, our vertex is the point (4, -2.5).

The axis of symmetry is equivalent to the x-coordinate of the vertex.

The x-coordinate of the vertex is 4.

Therefore, the axis of symmetry is x = 4.

O y-4 = 2(x + 4)

2.

the equation of the line in slope-intercept form is:

y = (1/2)x - 2

### What is the Linear equation?

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.

From the graph, two points on the line are (-4, -4) and (4,0),

The formula for the slope of a line is:

m = (y₂ - y₁) / (x₁ - x₁)

where (x₁, y₁) and (x₂, y₂) are two points on the line.

Using the given points (-4, -4) and (4, 0), we can calculate the slope:

m = (0 - (-4)) / (4 - (-4))

m = 4 / 8

m = 1/2

Now that we know the slope, we can use the slope-intercept form of a line, which is:

y = mx + b

where m is the slope and b is the y-intercept.

To find the y-intercept, we can use one of the givenpoints on the line. Let's use the point (-4, -4):

y = mx + b

-4 = (1/2)(-4) + b

-4 = -2 + b

b = -2

Therefore, the slope-intercept form of the line is y = (1/2)x - 2.

A

Step-by-step explanation:

For point-slope form, you need a point and the slope.

y - y₁ = m(x - x₁)

Looking at the graph, the points you have are (4, 0) and (-4, -4).  You can use these points to find the slope.  Divide the difference of the y's by the difference of the x's/

-4 - 0 = -4

-4 - 4 = -8

-4/-8 = 1/2

The slope is 1/2.  This cancels out choices C and D.

With the point (-4, -4), A is the answer.

Consider the statement p:x+9=10.which of the following is a equivalent statement

The equivalent expression for x+9=10 is x=1.

Step-by-step explanation:

We have a statement i.e. x+9=10

We need to find an equivalent statement for the above statement.

If we subtract 9 on both sides of the above statement,

x+9-9=10-9

We know that, 9-9=0 and 10-9 =1

x+0=1

x=1

So, the equivalent expression for x+9=10 is x=1.
