Yes, a plane containing 2 points of a line contains the entire line. Let us consider two points on a plane and then draw a line segment joining those two points. Since the points lie on the plane so line segment has to lie completely on that plane too. Now if we extend the line segment indefinitely in both directions we get a line and that line also has to lie on the same plane since some definite part(line segment) of it(line) also lies on the same plane.
A straight line may be extended in either direction indefinitely. A ray is the part of the straight line beginning at a given point and extending limitlessly in one direction. A line segment is a part of the straight line between two of its points, including the two points.
Points: (2, 6) and (-3, -4) Slope: 2
The straight line equation works out as: 3y = x
It would be a ray (one half of a line).In geometry "A set of points extending infinitely in one direction" is called a RAY.
Line is going down and to the right.

Greater 'x' ===> greater 'y' . Slope is positive. Line is rising toward the right.
As you move from left to right, the line is rising at an angle of 57.26° degrees above horizontal.
B. horizontal
Leftward straight.
A line containing the point 5 9 and -5 -5 is going from the bottom left to the top right. It is a positive slope.
what is the slope of the line containing points (5-,-2) and (-5,3)? 2
The Slope of a line containing the points (2,2) and (4,2) is Y=0
yes
Through any three points NOT on the same straight line. If they are all on the same line then that line can act as an axis of rotation for an infinite number of planes containing the three points.
