Calculate the difference of the y-coordinates, and divide it by the difference of the x-coordinates. That is the slope.
It work out as a 1/2 or 0.5
To find the slope of any line y = f(x) differentiate with respect to x: slope = dy/dx; the slope at any point can then be found by substituting the value of the x coordinate of that point. If you mean how to find the slope of a straight line: slope = change_in_y/change_in_x Taking any two points on the line (x0, y0) and (x1, y1) this becomes: slope = (y_of_first_point - y_of_second_point)/(x_of_first_point - x_of_second_point) → slope = (y1 - y0)/(x1 - x0) As it doesn't matter which is chosen as the first point, the slope can also be written as: slope = (y0 - y1)/(x0 - x1)
Points: (-1, -1) and (-3, 2) Slope: -3/2
Points: (-2, 7) and (2, 3)Slope: -1
Choose two distinct points from the table and designate their coordinates as x1, y1 and x2, y2. The slope of the line then will equal (y2 - y1)/(x2 - x1).

Slope of line: (y2 -y1)/(x2-x1)
true
The slope is calculated as: y1-y2/x1-x2 given two sets of points
Points: (-3, -1) and (3, -2) Slope: -1/6
You need two points before you can calculate the slope.
Points: (x, y) and (x, y) Slope: y1-y2/x1-x2

0). Considering any TWO points, you can calculate the slope of the line between them like this: Slope = (difference between the y-values of the two points) divided by (difference between the x-values of the two points). Use this technique to examine your THREE points, like this: 1). Calculate the slope of the line between Point-2 and Point-1. 2). Calculate the slope of the line between Point-3 and Point-1. 3). If the two slopes are equal, then the three points all lie on the same line.
You need two coordinates, not one, to specify a point. To calculate the slope, simply calculate (difference in y-coordinates) / (difference in x-coordinates).
When computing the slope of a line, choose two points along the line and do the following: Let's say the points we choose are (1,3) & (2,5). To compute the slope we need to use the slope formula: m = (y1-y2) / (x1-x2). So, using the two points we chose, just plug them into the formula: m = (3-5) / (1-2) = -2 / -1 = 2. Therefore, our slope is 2. These particular points yield the graph, y = 2x + 1.
