Which ratio is equivalent to 3/7? a) 6 to 10 b) 9: 12 c) 12/35 d) 7 to 3

we are ratio as

It will be equivalent to only those terms which would be multiple of this term

so, we will multiply top and bottom term by 5

and we get

so, it is very similar to 12/35

so, it will be equivalent to 12/35

so, option-C.......Answer

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
