Write using expanded notation.
the sum of a two-digit number and that number written backward.
x × 10 +y× 1, if the digits are a and b. ( and maybe brainliest )
solve for x and y

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
