## In Exhibit A-6, what is the slope of straight line AB? a. 1 b. 5 c. 1/2 d. −1

To determine

Value of the slope of the AB.

### Explanation of Solution

The slope of a line can be calculated by dividing the unitary change in the Y coordinates with the unitary change in the X coordinate as follows:

Slope=Unit change in Y coordinateUnit change in X coordinate=1020=12

Option (c):

The unit change in the Y coordinate is by 10 values upwards whereas the unit change in the X axis is by 20 units upwards which means that the slope of the line given is a positive value which is calculated to be 12
