ERROR ANALYSIS Describe the error in determining whether the lines are parallel, perpendicular, or neither. Line 1: (3,-5),(2, -1)
Line 2: (0,3),(1,7)

There is a sign error in finding m
The slopes of perpendicular lines are negative reciprocals of each other.
Two lines are parallel when their slopes have the same absolute value.
In Line 2, one point is on the x-axis, so only the y-values should be subtracted to find the slope.

Use the function f(x) is graphed below. the graph of the function to find, f(6). -2 -1 1 2

Which of the following contains a variable?

For a science project, a high school research team conducted a survey of local air temperatures. based on the results of the survey, the found that the average temperatures were around 10 degrees higher than expected. this result was wrong. the trouble with the survey was that most of the locations were exposed to direct sunlight and located over asphalt or sand, which resulted in higher temperatures than normal. this is a classic example of an error in which phase of inferential statistics?
