Answer:
-2
Step-by-step explanation:
We can use the slope formula to find the slope
m = ( y2-y1)/(x2-x1)
= ( 3-9)/(0- -3)
= (3-9)/(0+3)
= -6/3
= -2

Answer:
x=-2
y=8
Step-by-step explanation:
4x+2y = 8
4x+3y = 16
Subtract the first equation from the second equation
4x+3y = 16
-4x -2y = -8
---------------------------
0x +y = 8
y =8
Substitute this into the first equation to find x
4x+2(8) = 8
4x+16 = 8
Subtract 16 from each side
4x+16-16 = 8-16
4x = -8
Divide each side by 4
4x/4 =-8/4
x =-2
