Well, i'm just going to take a stab at this:
The answer out of:
> It is (18,9) ,
> It is (9, 18)
I believe both are correct as those are both plausible coordinates (although I may be wrong)
Line R: 2x + 2y = 18 (x + y = 9)
Line M: x + y = 9
There are infinite many solutions as they are the same line.
Answer:
-3
Step-by-step explanation:
y = -3x
This is in slope intercept form
y = mx+b where m is the slope and b is the y intercept
The slope is -3 and the y intercept is 0
Answer:
The constant of proportionality is always the point (x, k * f (x), where k is the constant of proportionality.
Step-by-step explanation:
Let's take as example a linear function of the form: y = kx.
Where, k is the constant of proportionality.
Therefore, the proportionality constant is the point: (x, kx)
Generically it is always the point: (x, k * f (x)
Where, f (x) is a function proportional to x. The constant of proportionality is always the point (x, k * f (x)), where k is the constant of proportionality.

Answer:
or 
Step-by-step explanation:
Given
Points:
A(-3,2) and B(-2,3)
Required
Determine the radius of the circle
First, we have to determine the center of the circle;
Since the circle has its center on the x axis; the coordinates of the center is;

Next is to determine the value of x through the formula of radius;

Considering the given points



Substitute values for
in the above formula
We have:

Evaluate the brackets


Eva;uate all squares


Take square of both sides
Evaluate the brackets



Collect Like Terms


Divide both sides by 2

This implies the the center of the circle is

Substitute 0 for x

Substitute 0 for x and y in any of the radius formula


Considering that we used x1 and y1;
In this case we have that; 
Substitute -3 for x1 and 2 for y1
