Answer:
- Carlton thinks that converting metric units is as easy as moving the <u>decimal point</u>
Step-by-step explanation:
- When you convert the unit, you move decimal point on your answer from the left to the right or from the right to the left the number of places as per relevant prefix.
<u>Example: </u>
- 1 meter = 1000 millimeters (1.0 m = 1000.0 mm)
- 1 milligram = 0.001 grams ( 1.0 mg = 0.001 g)

Two lines are perpendicular between each other if their slopes fulfills the following property
where m1 and m2 represents the slopes of line 1 an 2, respectively.
To find the slope of a line we can write it in the form slope-intercept form
Our original line is
Then its slope is
Now we have to find the slope of the second line. Using the first property,
Then the second line has to have a slope of 8.
The options given to us are:
Then we have to determine which of these options have a slope of 8. To do that we write them in the slope-intercept form:
Once we have the options in the right form, we note that the only one of them that has a slope of 8 is the last one.
Then the line perpendicular to the original one is
