Extension
on student sheet 44.2, you labeled the name and direction of move-
ment for eight major lithospheric plates. visit the issues and earth
science page of the sepup website for links to sites that show both the
name and direction of movement of the remaining plates. use this
information to label seven more plates on student sheet 44.2.

step-by-step explanation: you take each of the numbers and divide by the amount then you take the range

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

definitely a. the others have almost all data points on one side of the line.
