Draw a coordinate plane.
natulia [17]

The coordinate of points K, L and M is the location of the points on a coordinate plane

<h3>How to determine the missing coordinates?</h3>

The given parameters are:

K = (10, )

L = ( ,10)

M = (30, )

The question has missing parameters.

So, I will assume that the line is a perfectly horizontal line.

This means that the y-coordinates of points K, L and M are equal.

The y-coordinate of point L is 10.

So, we have:

K = (10, 10)

L = ( ,10)

M = (30, 10)

Assume that point L is halfway points K and M, then we have:

K = (10, 10)

L = (20, 10)

M = (30, 10)

See attachment for the diagram of the coordinate plane showing the line

4+4-3-4-2-5-1-8-9-0=a+c=a
lorasvet [3.4K]

Simplification of the expression gives 2a + c = -24

<h3>How to simplify the equation</h3>

4+4-3-4-2-5-1-8-9-0=a +c + a

First, let's add

8 -3 -4-2-5-1-8-9-0 = a+ c + a

Then, let's substract

-24 = a + c + a

<em />-24 = 2a + c

We then have,

2a + c = -24

Thus, simplification of the expression gives 2a + c = -24
