Suppose you are determining the growth rate of two species of plants. Species A is 12 cm tall and grows 2 cm per month. Species B is 10 cm tall and grows 3 cm per month. Which system of equations models the height of each species H(m) as a function of months m. H(m ) = 12 + 2m H(m ) = 3 + 10m H(m ) = 2 + 12m H(m ) = 3 + 10m H(m ) = 12 + 2m H(m ) = 10 + 3m H(m ) = 2 + 12m H(m ) = 10 + 3m

    `Species A is 12 cm tall and grows 2 cm per month. ` we start at 12 add 2 cm each month so we have 12 + 2m where m is the number of months

    `Species B is 10 cm tall and grows 3 cm per month` similar to species A, we have 10+3m

    H(m ) = 3 + 10m is not correct because this says `start at 3 and increase by 10 each month`

    (c) has \[H(m ) = 12 + 2m\]\[ H(m ) = 10 + 3m\] The first equation has a \(y\)-intercept of \(12\) and a slope of \(2\), so it represents a plant with height \(12\) at \(t=0\) and growth of \(2\) per unit of \(t\). The second equation has a \(y\)-intercept of \(10\) and a slope of \(3\), so it represents a plant with height \(10\) at \(t=0\) and a growth of \(3\) per unit of \(t\). These match how the growth of species A and B is described.
