parallel, perpendicular, graphing, linear equation, slope, lines
we know that
If two <u>lines</u> are <u>perpendicular</u>, then the product of their <u>slope</u> is equal to minus one
so
If two <u>lines</u> are <u>parallel</u>, then their <u>slope</u> are equal
In this problem we have
--------> <u>linear equation</u> A
the <u>slope</u> is
--------> <u>linear equation</u> B
the <u>slope</u> is
Find the product
---------> the <u>lines</u> are <u>perpendicular</u>
therefore
the answer is the option B
Perpendicular

Answer:
1 light-minute ≈ 1.12×10⁷ miles, three significant figures.
Step-by-step explanation:
Light-second is equal to the distance traveled per second by light in space, which is equal to 299,792,458 metres. Other units used are light-day, light-hour and light-minute.
Significant figures are the figures or digits of a number that carry meaning and contribute to the precision of the given number.
1 light-minute = 1.118×10⁷ miles, has four significant figures.
To express this number in three significant figures, the given number is rounded.
<u>1 light-minute = 1.118×10⁷ miles ≈ 1.12×10⁷ miles, has three significant figures, as the non-zero digits are significant.</u>
