A growing plant has its mass and water uptake measured with the following results:

Time (Days) 1 2 3 4 5 6

Mass (g) 6.37 10.10 13.54 17.45 20.32 24.90

H₂0 Uptake (mL/h) 0.20 1.21 1.79 2.46 3.23 4.21

a) formula for M as a linear function of t. (Plot accurately on graph paper, or create

points in geogebra, then draw/create a line that follows the points.)

b) Use your function to estimate when the plant's mass reached 15g.

c) Plot the plant's water uptake (U) as a function of time (t) and determine an

appropriate formula to estimate this relationship with a linear function.

d) Use your function to estimate the plant's water uptake at the time from part b).
