Write the normal form of the equation: 9x-2y+4=0


a. 9/ sqrt 85x-2/ sqrt 85y+ 4/ sqrt 85 =0

Y=4.5x+2
Subtract 9x and 4, moving them to the other side
Divide that side by negative 2

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)

Skew lines(segments) are lines(segments) in 3 dimensions that do not intersect the given segment and are not parallel to it.  ae, bf, eg, and fh are your skew segments.  i hope that : )
