The slope is the change in y divided by the change in x ("rise over run").
For the points (x1, y1) and (x2, y2), the slope calculation is:
( y1 - y2 )
( x1 - x2 )
For the points (3, -9) and (7, 6), the slope calculation is:
( -9 - 6 ) = ( -15 ) = 3.75
( 3 - 7 ) ( -4 )
Since the line is horizontal, the slope is zero.
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).
The slope is -9.
Points: (5, -1) and (2, -5) Slope: 4/3 Perpendicular slope: -3/4
1:5
Another set of points are needed to find the slope.
Since the line is horizontal, the slope is zero.
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).
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.
-1/4
The slope is -9.
Points: (1, 5) and (0, 2) Slope: 3
84
The slope is -9.
17
If the line passing through these points is a straight line then it has a positive gradient.
