1. A rhino's weight, when rounded to the nearest thousand, was 10,000
pounds. Which of these is the least the rhino could have weighed?
VA) 9,500 pounds
(B) 9,001 pounds
(C) 10,499 pounds
(D) 9,999 pounds

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
