Answer:
slope: 2/3 or 0.6666...
Step-by-step explanation:
find two points on the line : (1,2) and (0,-2) and do rise over run. Rise = 2 and Run = 3, so you put it in rise over run form. Rise/Run = 2/3. The graph is positive.
x=9
Remove the radical by raising each side to the index of the radical.
y = - 4x + 20 ... slope=-4 y intercept:20
2y+8x=20
2y=-8x+20
(y = mx + b)
37/9 = (4x9)+ 1/9
The mixed fraction is 4 and 1/9
