Answer:
A. -1/5
Step-by-step explanation:
The y increases by 3 and the x decreases by 15. Utilizing rise/run form (y/x,) you get -1/5.
C.)-5
y2-y1/x2-x1
(-9,6) (-6,-9)
-9-6=-15
-6-(-9)=3
-15/3=-5
The 3 units from 12 on a number line is 4units
2x2 - 5x - 12 = 0.
(2x + 3)(x - 4) = 0.
2x + 3 = 0 or x - 4 = 0.
x = -3/2, or x = 4. I hope this helps
