To determine which ordered pair is a solution of the equation y=3x, we substitute the x and y values of each ordered pair into the equation and see which one makes the equation true.
a. (-2,-9):
When x = -2, the equation becomes:
-9 = 3(-2)
-9 = -6 (Not true)
b. (-8,-18):
When x = -8, the equation becomes:
-18 = 3(-8)
-18 = -24 (Not true)
c. (-8,-3):
When x = -8, the equation becomes:
-3 = 3(-8)
-3 = -24 (Not true)
d. (-10,-30):
When x = -10, the equation becomes:
-30 = 3(-10)
-30 = -30 (True)
Therefore, the ordered pair (-10,-30) is a solution of the equation y=3x.

b. (-8,-18)
c.(-8,-3)
d. (-10,-30)
