Final answer:
The slope of line t is 7/6, which is the same as the slope of line s.
Step-by-step explanation:
The slope of a line can be found using the formula: slope = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of two points on the line.
For line s passing through points (7,9) and (1,2), we can assign (x1, y1) as (7,9) and (x2, y2) as (1,2). So the slope of line s is: slope = (2 - 9) / (1 - 7) = -7 / -6 = 7/6.
Since line t is parallel to line s, it will have the same slope. Therefore, the slope of line t is also 7/6.
