The coordinates of W on the number line is 3
The complete question is added as an attachment
From the attached figure, we have the following parameters:
A = -7
F = 5
The ratio is given as:
Ratio = 1 : 3
This means that the location of point W on the number line is:
W = 1/(1 + 3) * |F - A|
Substitute the known values in the above equation
W = 1/(1 + 3) * |5 + 7|
Evaluate the sum
W = 1/4* |12|
Remove the absolute bracket
W = 1/4 * 12
Evaluate the product
W = 3
Hence, the coordinates of W is 3
