the height of a certain plant can be modeled by the formula h=3t+7 where h is the height in millimeters and t is the time in days. which of the following best describes the independent variables in this model?

what?

step-by-step explanation:

he has now walked a total of what?

if i know what this is maybe i can

step-by-step explanation:

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

3

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3
