I need an answer as soon as possible.

Answer 1

The slope of line AB is also 1/2.

The slope of a line can be found using the formula:

`m = (y2-y1)/(x2-x1)`

where ((x_1, y_1)) and ((x_2, y_2)) are two points on the line.

Given that points A, B, C, and D are colinear and the slope of CD is 1/2, we can find the slope of line AB using the fact that the slope of the line between any two points is the same.

Since points A, B, C, and D are colinear, the slope of line CD is equal to the slope of line AB. Therefore, the slope of line AB is also 1/2.
