Colin purchases a plant from a gardening store. The height of the plant, in centimeters, after different numbers of weeks is shown in the table.

The height of Colin’s plant, in centimeters, can be modeled by the given equation, where $h$ is the height of the plant and $w$ is the number of weeks since he purchased the plant.

${h}=0.5 {w}+12$

On the same day that Colin purchases his plant, Megan purchases a plant that has a different height than Colin’s plant and that grows faster than Colin’s plant. Megan also uses a linear equation to model her plant’s growth. Complete the sentences to describe an equation that could model the height of Megan’s plant.

The slope in Megan’s equation $\ldots \ldots$ the slope in Colin’s equation.
