Which linear inequality is represented by the graph? O y>_ 1/3x-4
O<_1/3x-4
O<_1/3x+4
O>_1/3x+4

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )

faster, im not sure why but i know it is faster

answer:

at time x=0 we have 1000, at time x=1 we have 2000, at time x=2 we have 4000.  

so that's an initial value of 1000 and a ratio of 2,

y = 1000 (2^x)

hope this !
