The population of bacteria in a petri dish is modeled by the function p(t)=2t , where t is time in minutes after an experiment began.

what is the average rate of population growth per minute between the end of the first minute and the end of the sixth minute?

y = 3x+4

step-by-step explanation:

to find the slope

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

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
