One line passes through the points (-7, 4) and (5, -4). Another line passes through points (-7, -4) and (2, 2). Are the lines parallel, perpendicular, or neither?

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

We just need to find the slope of both lines.

_________________________________

IF their slopes are same they are parallel.

++++++++++++++++++++++++++++++++++++

IF their slopes are negative and inverse with each other , they are perpendicular ,

thus when we multiply them the answer must equals - 1 .

Which means :

slope ( L 1 ) × slope ( L 2 ) = - 1

++++++++++++++++++++++++++++++++++++

And Neither when none of above phrases happened.

_________________________________

LINE (1)

A = ( - 7 , 4 ) & B = ( 5 , - 4 )

We have following equation to find the slope using two points :

Now just need to put coordinates in the above equation :

##############################

LINE (2)

C = ( - 7 , - 4 ) & D = ( 2 , 2 )

Put the coordinates.

_________________________________

CHECK ;

Thus they are not parallel .

Thus they are not perpendicular.

So Neither.

the monthly balance will be $75,000

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

happy to

pls mark as brainliest.
