Find the slope of the line containing the given two points, then say if the line rises, falls, horizontal or vertical. (-5,-2) and (5,-2)

This slope is horizontal and the slope is 0.

Step-by-step explanation:

In order to find this, we simply need to use the slope formula.

m(slope) = (y2 - y1)/(x2 - x1)

m = (-2 - -2)/(5 - -5)

m = (-2 + 2)/(5 + 5)

m = 0/10

m = 0

Slopes that are equal to 0 are horizontal because there is no change in the y value.

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)

probably the last option
