No. If you have more than two points for a linear function any two points can be used to find the slope.
Not always. For example, try to find the slope of the line that passes through the points (3, 4) and (2, 3).
Points for example: (4, 8) and (2, 4) Slope: (8-4)/(4-2) = 2 The slope formula is m = (y2 - y1) / (x2 - x1) where the 2 points are (x1,y1) and (x2,y2)
Points: (2, 3) and (2, 9)Slope: 0The line is vertical and parallel to the y axis
Another set of points are needed to find the slope.
That depends on the points in order to find the slope whereas no points have been given.
To find the slope of a line passing through two points, use the formula (y2 - y1) / (x2 - x1). In this case, the two points are (17, 101). Since there is only one given point, it is not possible to find the slope of the line passing through these points.
To find the slope of a line passing through a given pair of points is found by using the point slope formula. Y(2)-Y(1) over x(2) -x(1).
y=mx+b
Since the line is horizontal, the slope is zero.

No. If you have more than two points for a linear function any two points can be used to find the slope.
