Verified Answer :

the slope= y/x
the run = x

1/2 = y/50
cross multiply
2y = 50
y = 50/2
y = 25 <=== the rise

Answer: A) 25

Step-by-step explanation:

Since, Slope of a line, m = \(\frac{rise}{run}\)

But According to the question Slope of the given line, m = \(\frac{1}{2}\)

Therefore, \(\frac{rise}{run}\) = \(\frac{1}{2}\)

But run =50,

⇒\(\frac{rise}{50}\) = \(\frac{1}{2}\)

⇒ rise = 1/2 × 50 = 25

Thus, Rise = 25.

So, Option A) is correct.
