Question

vera cintron, kirialys
a unit 2 practice problem
georgia did a project in which she measured the change in height (inches) that plants grew for different amounts of water (ounces) they were given each day. after one week, her data
created the linear equation ( y = 1.47x - 2.43 ) to describe the correlation.
what is the meaning of the slope in this equation?
\\( \circ \\) for every additional seed planted, 1 plant grows another 1.47 inches.
\\( \circ \\) for every additional ounces of water, her plants grow another 2.43 inches.
\\( \circ \\) for every additional ounce of water, her plants grow another 1.47 inches.
\\( \circ \\) for every additional inch a plant grows, it needs another 1.47 ounces of water.

Explanation:

The given linear equation is in the form $y = mx + b$, where $m$ (the coefficient of $x$) is the slope. Here, $x$ represents ounces of water and $y$ represents plant height change. The slope 1.47 means the change in $y$ per unit change in $x$.

Answer:

For every additional ounce of water, her plants grow another 1.47 inches.
