Question

Which of these are the ordered satisfy the equation Y=-9x

A. (0, 0)
B. (2,-18)
C. (4, 36)
D. (-3, -27)
E. (-2, 18)
F. (-1, -9)

Answer 1

to figure out which ordered pair are or are not on the line
plug in for x and y based on (x, y)
so for example F. (-1. -9)
plug in x = -1 and y = -9 into y = -9x
so (-9) = (-9)(-1)
and you get -9 = 9
but -9 does not equal 9
therefore ordered pair (-1, -9) does not work

and you get do this for all the ordered pairs :)
