A science experiment begins with a metal at negative hundred degrees Celsius the following function describe the temperature change per minute F(X) = 89x - 100° how old the graph of this function change if the metal is at 25° at the start of the experiment.

A)The line will shift vertically up by 125°
B) The one shift verticay up by 25°
C) The line will shift vertically down by 125°
D) The Line will shift vertically down by 25°
Please help as soon as possiable! :) Thank you so much. My teacher gave me this in a practice assignment and I would really like if someone can help me!
