Final answer:
The rise of a line with a slope of 1/2 and a run of 50 is calculated by multiplying the slope with the run, which results in a rise of 25.
Step-by-step explanation:
To find the rise of a line with a given slope and run, we use the formula of slope which is defined as the rise over the run. The slope (m) is given as 1/2, and the run is 50. Therefore:
Slope (m) = Rise / Run
1/2 = Rise / 50
Now we solve for the rise:
Rise = 1/2 * 50
Rise = 25
So the rise of the line is 25, which means that option a) (25) is the correct answer.
