Answer:
Step-by-step explanation:
y=mx+b where m=slope and b=y intercept
m=(y2-y1)/(x2-x1)
m=(-2-4)/(2+1)
m=-2 so far we have the slope
y=-2x+b, using point (2,-2) we can solve for b, the y intercept
-2=-2(2)+b
-2=-4+b
2=b so we have our line
y=-2x+2, slope is -2 and y intercept is 2
Answer:
no they are not because 11, 14 is the only one that has a vertices
Step-by-step explanation:
The slope is 16/4 which is 4/1 which can also be 4. So the most simplified is 4
PH = -log[H+]
= -log(2*10^-9)
= -(log(2) +log(10^-9))
= -(0.3 -9)
= 8.7
The appropriate choice is
C. 8.7
