Choose two x, y coordinate pairs from your table. Then use the slope formula:
where and are the coordinates of the given points to calculate the slope of the line containing the line segment joining the two selected points. Keeping one of the original coordinate pairs, select a different second coordinate pair and perform the same slope calculation. If both slopes are identical, assume that your data is linear.
Using the calculated slope and the -coordinate of the point where your data intersects the -axis, namely the -coordinate of the -intercept, construct a slope-intercept form equation:
where is the calculated slope and is the -coordinate of the -intercept.
