The amounts of household waste generated in a region during two years
were 23,400,000 tons and 48,100,000 tons. What was the total
household waste generated over these two years in the region,
expressed in scientific notation?
7.15 - 10x7tons
7.15 - 10x14 tons
71.5 - 10x7 tons
71.5 - 10x14 tons

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
