Ravi had 8/9 acres of land. he planted 2/5 of it with corn. how many acres did he plant with corn?

First, find the common denominator of both fractions.

8/9 = 40/45

2/5=  18/45

Subtract 18/45 from 40/45

40/45 -- 18/45 = 22/45

Your answer is 22/45.

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
