What is the answer to this equation

the equation of the following line (0,0) and (-3,1)

First we find slope of the line using the given points (0,0) and (-3,1)

(0,0) is (x1,y1)  and (-3,1) is (x2,y2)=

=

Now we use equation y=mx+b

where m is the slope and b is the y intercept

Plug in (0,0) and solve for b

b=0

So equation of the line is

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:
