Chemistry question (1st order integrated rate law) - Calculating time at 68.9%

completion? A reaction of the form
aA Products
gives a plot of [A] vs time(in seconds) which is a straight line with a slope of –6.90 x 10-2. Assuming [A]o = 0.100 M, calculate the time (in seconds) required for the reaction to reach 68.9 percent completion.

Please work this out for me...I thought I was doing it right, but apparently not! Thank you.
