Using the general format of a line, y = mx + c,
Where m = slope of the line, c = vertical intercept.
y = -3x -3, comparing to y = mx + c
Slope, m = -3, vertical intercept, c = -3.
For a negative slope, the line would be falling downwards from the left hand side of graph sheet to right hand side.
Slope = -3,
Vertical or y intercept is the point it cuts across the y axis, at this point, x = 0
y intercept = (0, -3)
x intercept, at this point, the value of y is zero.
y = -3x - 3
0 = -3x - 3
0 + 3x = -3
3x = -3
x = -3/3
x = -1.
x intercept = (-1, 0)
So we would plot the points (0, -3) and (-1, 0)
See attached picture for sketch of the line y = -3x - 3.
To compare 13lb with 22lb as a ratio just put 13lb over 22lb as a fraction because they're the same in pounds: 13lb/22lb.
The better statistics that can be used to compare the scores of the two teams are: <u>D. Median and IQR.</u>
- The diagram given shows two box plots representing the data of the two team's scores.
<u><em>Box plots</em></u><u><em> displays the </em></u><u><em>5-number summary</em></u><u><em>, namely:</em></u>
- Minimum data value
- Maximum data value
- Median
- First Quartile
, and - Third Quartile

The Interquartile Range (IQR) of the data can also be calculated by finding the difference between the First Quartile
, and the Third Quartile
.
The Interquartile Range (IQR) helps us to determine the variability of the data set.
The median that is gotten from the box pot measures the center tendency of the data.
Both median and IQR are better statistics that can be easily gotten from box plots to compare the team scores.
Therefore, the better statistics to use for comparing the scores of the teams are: <u>D. Median and IQR.</u>
