Question each-d

3.4 Two-Variable Data & Models - Line of best fit
0:00
The figure presents a sterplot. The horizontal axis is labeled “High jump height, in feet,” and the numbers 0 through 6, in increments of 1, are indied. The vertical axis is labeled “Long jump distance, in feet,” and the numbers 0 through 20, in increments of 2, are indied. There are 20 dots indied on the sterplot. The dots begin in the lower left part of the plane, at the dot with coordinates 1 comma 2, and trend upward and to the right until they end in the upper right part of the plane, at the dot with coordinates 5 comma 15.

Each dot in the sterplot above represents the height x, in feet, in the high jump, and the distance y, in feet, in the long jump, made by each student in a group of twenty students. The graph of which of the following equations is a line that most closely fits the data?

A.

y equals, 0 point 8 2 x, plus 3 point 3 0

B.

y equals, 0 point 8 2 x, minus 0 point 8 2

C.

y equals, 3 point 3 0 x, plus 0 point 8 2

D.

y equals, 3 point 3 0 x, minus 3 point 3 0
