Determine the slope of the line that has the following coordinates: (0, -3) (2, 1)

5

Step-by-step explanation:

The slope of a line, m, is defined as

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

In this case we have points (0,-3) and (2,1) so

m=(1-(-3))/(2-0)

m=4/2

m=2

So the slope of the line is 2

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:

i think this could be a possible answer (1 / 84) -1

good luck! : d
