Answer:
<em>Centimeters of crystal ( in real life ) = 0.5 cm</em>
Step-by-step explanation:
Let us plan out our steps, and solve for each:
1. Given the information, let us create a proportionality as such:
24 = 1 ⇒ x - <em>crystal size in real life</em>
12 x
3. Now let us cross multiply, and solve through simple algebra:
12 = 24 * x,
<em>x = 0.5 centimeters of the crystal in real life</em>

x=2,25
Answer:
y = 1/2x - 7
Step-by-step explanation:
y = 1/2x + b
-4 = 1/2(6) + b
-4 = 3 + b
-7 = b
