Answer:
The type of association between x and y are inversely proportional
Step-by-step explanation:
Solution:
Here the x value increase, the y value decrease which implies that x is inversely proportional to y
I hope this helps.
Answer:
Step-by-step explanation:
5) P1=(x1,y1) P2=(x2,y2)
P1=(0,1) P2=(4,-1)
m = y2-y1 / x2-x1
m= -1-1 / 4-0
m= -1/4
point-slope formula (memorize this ) [y-y1=m(x-x1)
y-1= -1/4(x-0)
y-1 = -1/4x
y= -1/4x+1
6) P1=(-3,3) P2=(0,-1) ( same process as above)
m=-1-3 / 0-(-3)
m= -4/3
y-3= -4/3(x-(-3))
y-3 = -4/3(x+3)
y-3 = -4/3x -4
y = -4/3x -4+3
y = -4/3x -1
7) P1=(0,-1) P2=(-2,-2) (same process as above)
m= -2-(-1) / -2-0
m= -2+1 / -2
m= -1 / -2
m= 1/2
y-(-1) =1/2(x-0)
y+1= 1/2x
y= 1/2x -1
8) P1=(1,-5) P2=(-2,2)
m=
I'll let you work out the rest of 8.. just follow what i've shown above.. ask later if you need more help :)
