Match the portion of the graph with the corresponding equation that represents
the number of pedestrians (y) walking on the pavement during different parts of
the day (x).
B.

y = 600
y 300 + 100x
y = 900 - 90x

To know whether there is a relationship between two variables, you draw a line around the outer edges of a scatterplot. If there is a negative relationship,
Group of answer choices
the scatterplot is elliptical and is slanted upward (low left to high right).
the scatterplot is either circular or elliptical, and the ellipse is parallel to the X axis.
the scatterplot is elliptical and is slanted downward (high left to low right).
the scatterplot is simultaneously elliptical and circular.
