Solve the system of equations.
0.8x + 0.1y = -2
-0.17x + y = -3.66
A( 4, 2)
B(2, 1)
C(-2,-4)
D(-10, 12)
E(-12, 12)

A) .8x + .1y =-2

B) -.17x + y = -3.66

We multiply A) by -10

A) -8x  -y = 20  then add it to equation B)

B) -.17x +y = -3.66

-8.17x = 16.34

x = -2

-1.6 + .1y = -2

.1y = -.4

y = -4

Answer is C)

Step-by-step explanation:

last one.

step-by-step explanation:

last one.

generally speaking, the others follow some sort of pattern that correlates to either linear (looks like a straight line) or sinusoidal (looks like an s).

the last one is just a random cloud of points that doesn't correlate to any particular known order.

f is the midpoint of
