Answer:
y=x+5 graph points: (0,5), (-5,0)
y=x-3 graph points: (0,-3), (3,0)
Step-by-step explanation:
These equations are in slope-intercept form.
y=mx+b
m=slope
y= y-intercept
I graphed the lines based on the equations and gave the two points of each equation where the line intersected the x and y axis.

The half life of the substance is 6.92 days.
<h3>What is the Half life ?</h3>Half life can be defined as the time required to reduce the concentration to half of its initial value.
Here the equation given is
The concentration will reduce to half therefore
so,
ln 0.5 = - 0.1001 * t(1/2)
-0.693 = -.1001 * t(1/2)
t(1/2) = 6.92 days.
Therefore the half life of the substance is 6.92 days.
