2. a rectangular prism has e flat surfaces . 3, a cone h as -flat surface. a cube has 요 flat surfaces.

Step-by-step explanation:

The best-fit line is:

Predicted height = 0.32 · Days in Soil − 1.72

This equation is a line written in slope-intercept form:

y = mx + b, where m is the slope and b is the y-intercept.

The slope has units of y/x, and the y-intercept has units of y.

The slope is 0.32.  It has units of height / time = cm / day.

The slope is positive, so we expect the height to increase 0.32 cm in 1 day.

The y-intercept is -1.72.  It has units of height = cm.

The y-intercept is the height on day 0.
