The one(s) where the y coordinate is:
depending upon which of the following equations is intended (as there are missing operators in the question):
[Note equations 1 & 3 are the same equation written in different forms.]
If: y = -5x+3 then the points are (2, -7) and (6, -27)
-1
If you were to have 3 points on the same line, then you would actually not be determining a plane, because there are infinitely many planes that can intersect a given line. But if you have 3 points in the form of the points (or vertices) of a triangle, then you determine a plane in the sense that there is only one possible plane upon which that triangle can be drawn (not including a degenerate triangle, which is equivalent to a line).
From the given points the slope of the line works out as 3/4
Answer: y = -2/5x-14/5 which also can be written as 5y = -2x-14 or in the general form of the equation of a straight line as 2x+5y+14 = 0
If: y = -5x+3 then the points are (2, -7) and (6, -27)
If you mean points of (2, -3) and (4, 2) then the slope is 5/2 and the straight line equation is 2y = 5x-16
Slope: -5 Points: (6, 3) Equation: y = -5x+33
It has the same slope as the line in the question. If a line has equation y = mx + c, its slope is m. If the line in question is y = 5x + 3, the slope of a parallel line is 5; If the line in question is y + 5x = 3 → y = -5x + 3 (subtract 5x from both sides), the slope of a parallel line is -5.

It is every point in the plane that lies on the straight line defined by the equation -5x + 4y = -3. Since there are an infinite number of points on that line, there is no point in trying to list them.
If you mean of points of (3, -4) and (5, 1) then the equation works out as 2y=5x-23
Equation of the straight line: y = -3/5x+2 in slope intercept form
-1
Slope: 5 Points: (-2, -3) Equation: y = 5x+7
That depends what else is given, but basically you must find another line that has the same slope. For example, in y = 5x + 3, 5 is the slope; any other line with the same slope is parallel, for instance, y = 5x + 10, or y = 5x - 2.
