Question

A science experiment begins with a metal at −100° Celsius. The following function describes the temperature change per minute: f(x) = 89x − 100°. How will the graph of this function change if the metal is at 25° at the start of the experiment? (1 point)

Group of answer choices

The line will shift vertically up by 125°.

The line will shift vertically down by 125°.

The line will shift vertically up by 25°.

The line will shift vertically down by 25°.

Answer 1

the line will shift vertically up by 25 degrees

Explanation:

I just did the test :)

Answer 2

A: The line will shift vertically up by 125°.

Explanation:

So, the experiment starts with the metal at -100° then the start temperature changes to (positive) 25°. All you have to do is calculate how far away -100 is from 25. To calculate this, add 100 (for -100°) and 25 (for 25°) which equals 125. On the chart the line will shift vertically up
