The equations are written in point-slope form. which equation represents a line through points (–8, 3) and (–2, –3)?
y-3=-3(x+8)
y-3=3(x+8)
y-3=1(x+8)
y-3=-1(x+8)

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
