Hey there! Hello!
This can be represented by the equation y=2.54x, where:
y=measurement in inches
x=measurement in cm
You can plug any value into this problem to reveal that this is a linear function. I provided a graph of this to further prove the point.
Hope this helped you out, feel free to ask any additional questions if you need further clarification! :-)

Answer:
<em>u</em> = 7.21
Step-by-step explanation:
The magnitude of <em>u</em> is just the distance between the two points. The coordinates of the left-most point are (-2,-8) and the coordinates of the right point are (4, -4). I'm assuming the x coordinates here because we don't actually know the scale.
Ok so from these points, you can draw a triangle (u can see it in the attached file).
From the coordinates we can tell the lengths of the sides, and the triangle shows that <em>u</em> is the hypotenuse of the triangle. This triangle is also a right triangle, so u can use Pythagoras' theorem to find the length of <em>u</em>.
Since c = <em>u</em>, we know now that the magnitude of <em>u</em> is 7.21
Hope this helps!
