Use the table of values to identify the mathematical model that would best fit the data.
1 answer:
<h3>Answer:</h3>
y = -4.2x +34
<h3>Step-by-step explanation:</h3>The differences between adjacent y-values are -4.2 for all data points given, so the data is best modeled by a linear function with a slope of -4.2. The value for x=0 (the y-intercept) will be 4.2 higher than the value for x=1, so will be 34.
Thus the model can be ...
... y = -4.2x + 34

<em>Comment on the attached graph</em>
The graph shows an attempt to model the data with a quadratic function (the first on your answer list). The result is that the x² coefficient is zero, and the model is the equation of a line (as shown above).

<u><em>Process to construct the bisector of a line segment :</em></u>
<u><em>Step 1 :</em></u> Make the compass length ( the distance between the pointed leg and the pencil leg) slightly greater than half the length of the line segment OP. Place the point of the compass on O. Make arcs above and below the line segment OP.
<u><em>Step 2 :</em></u> Using the same compass length as same as the previous one, place the point of the compass on P. Make arcs above and below line segment OP. These arcs must intersect the arcs made in previous step.
<u><em>Step 3 :</em></u> Connect the points where the arcs intersect. Label the line segment MN and the point where the line intersects OP, Q.
<u><em>Step 4 :</em></u> Line segment MN bisects line segment OP at midpoint Q.
