Coordinates - Quiz 1    Question

Question 1

What is the point plotted?

a)		(4,3)		b)		(4,4)
c)		(3,4)		d)		(3,3)

 

Your answer is correct.

Not correct. Choice (b) is false.

Try again, you may have misread the point.

Not correct. Choice (c) is false.

Try again, you have swapped the x and y coordinates. The x coordinate is always first.

Not correct. Choice (d) is false.

Try again, you have misread the point.

Question 2

What is the point plotted?

a)		(-2.5,-2)		b)		(-2,-2.5)
c)		(-1.5,-2)		d)		(-2,-1.5)

 

Not correct. Choice (a) is false.

Try again, you may have misread the negative number.

Not correct. Choice (b) is false.

Try again, you may have misread the negative number and swapped the and coordinates.

Your answer is correct.

Not correct. Choice (d) is false.

Try again, you may have swapped the and coordinates. The coordinate is always first.

Question 3

Which of the following plots the point (-2.5,3)?

a)				b)
c)				d)

 

Not correct. Choice (a) is false.

Try again, this is the point (-1.5,3), you have misread the negative number.

Not correct. Choice (b) is false.

Try again, this is the point (3,-2.5), you have swapped the and coordinates.

Your answer is correct.

Not correct. Choice (d) is false.

Try again, this is the point (-1.5,-3), only the coordinate should be negative, you have also misread the coordinate.

Question 4

Which set of points are plotted?

a)		(-3,-1), (-2,1), (0,0), (0,3), (1,2), (2,0), (3,-2).
b)		(-2,3), (-1,-3), (0,0), (0,2), (1,-2), (3,0), (2,1).
c)		(-3,-1), (-2,1), (0,0), (0,2), (2,1), (3,0), (3,-2).
d)		(-3,-2), (-1,2), (0,0), (0,3), (2,-1), (2,0), (3,-1).

 

Your answer is correct.

Not correct. Choice (b) is false.

Try again, you have swapped the x and y coordinates.

Not correct. Choice (c) is false.

Try again, you have some of the coordinates plotted correctly but (0,2), (2,1), (3,0) not are plotted.

Not correct. Choice (d) is false.

Try again, only the points on the axes are correct.

Question 5

Which of the following plots most accurately represent the data below?

Initial level	-4.0	-3.1	-1.8	1.0	2.9
Final level	-0.9	-0.6	0.2	1.5	2.5

a)		Plot of final level vs initial level		b)		Plot of initial level vs final level
c)		Plot of final level vs initial level		d)

 

Your answer is correct.

The Initial Level needs to be plotted on the -axis and the Final Level on the -axis.

Not correct. Choice (b) is false.

Try again, you have plotted the values of the Initial Levels and Final Levels the wrong way around.

Not correct. Choice (c) is false.

Try again, it is usual to put the first row as the independent variable. It is not technically incorrect but Initial Level should be the -axis and Final Level the -axis.

Not correct. Choice (d) is false.

Try again, the plot has no proper title and the axes no labels, the first two points are plotted correctly but the other 3 are the wrong way around.
