Slope of line: (y2 -y1)/(x2-x1)
You need two points before you can calculate the slope.
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)
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.
False. When solving for the slope of the best fit line, you should consider all data points in your dataset to find the line that best fits the overall trend. Choosing points closest to the line or on the line may bias your results and not accurately represent the relationship between the variables.

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.
