Subtract 4x^2-5xy+9y^2 from 6x^2+4xy-7y^2

2x2 - 16y2 + 9xy

(the 2 to the right of the x and y are small numbers i forgot what dey are called lol)

ok i got your answer you hath to take out all those x,y s and you will get this 4^{2}-5+9^{2}-6^{2}+4-7^{2}equals 11

HOPE I HELPED PLZ GIVE ME A THANKS

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.

my dear correct answer is option number 3
