Answer:
x=-5, y=-2. (-5, -2).
Step-by-step explanation:
x-3y=1
-x+6y=-7
----------------
3y=-6
y=-6/3
y=-2
x-3(-2)=1
x+6=1
x=1-6
x=-5
Answer:
x = -18
Step-by-step explanation:
1/2x = -9
(21)1/2x = -9(2/1)
x = -9/1(2/1)
x = -18/1
x = -18
The slope is the change in Y over the change in X.
(-9,6) is X1 and Y1.
(-3,9) is X2 and Y2.
Slope = Y2-Y1 / X2-X1
Slope = 9 - 6 / -3 - (-9)
Slope = 3/6 = 1/2
The slope = 1/2
