Final answer:
To find the value of 'W' using the given slope of a line and the points (6, W) and (15, -3), we solve the equation 1 = (-3 - W) / (15 - 6). By solving for 'W', we determine that the value of 'W' is -12.
Step-by-step explanation:
The student is likely asking for slope calculation in mathematics, specifically finding the value of 'W' when given two points on a line. Despite the presence of some typos in their question, the essential part is that we have a line crossing through the points (6, W) and (15, -3), and the slope of this line is 1. We can calculate the slope of a line using the formula slope = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are coordinates of two distinct points on the line.
To find the value of 'W', we use the given slope of 1 and set up the equation as follows: 1 = (-3 - W) / (15 - 6). Solving for 'W', we get:
- 1 = (-3 - W) / 9
- 1 * 9 = -3 - W
- 9 = -3 - W
- W = -3 - 9
- W = -12
Therefore, the value of 'W' is -12.
