The coordinates are: (-4, -6) and (12, 2)

It is the parabola such that the coordinates of each point on it satisfies the given equation.

There are infinitely many "solutions". In the Cartesian plane, the coordinates of any point on the line defined by y = x + 2 is a solution. Thus, any ordered pair, (x, x+2) is a solution.

4x + 2(3x) = 30 10x = 30 x= 3. Y= 9. (3,9)

The coordinates of the point of intersection is (1,1).

If you mean the coordinates of the line x-y = 2 that intersects the curve of x2-4y2 = 5 Then the coordinates work out as: (3, 1) and (7/3, 1/3)

If the coordinates of the end points are (a,b) and (c,d) then the midpoint is the point whose coordinates are [(a+c)/2, (b+d)/2]

Use Pythagoras' Theorem: calculate the square root of ((difference of x-coordinates)2 + (difference of y-coordinates)2).

All you have to do is add the numbers and determine how much the numbers change. In your case, the new coordinates are (0, -1), (4, -2), (2, -6).

To find the midpoint, you find the mean (average) of each direction's coordinates. The average of the x coordinates is (9+7)/2 = 8. The average of y coordinates is (11+8)/2 = 9.5, So the midpoint is (8,9.5). This same method works for 3 and higher dimensions.
