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

Not correct. Choice (b) is false.

Try again, you may have misread the point.

Your answer is correct.

Not correct. Choice (d) is false.

Try again, you have misread the point.

Question 2

What is the point plotted below?

a)		(1.5,-2).		b)		(-3.5,1.5).
c)		(-2.5,1.5).		d)		(1.5,-2.5).

 

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.

Not correct. Choice (c) is false.

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

Your answer is correct.

Question 3

Which of the following plots the point (-2,-1.5)?

a)				b)
c)				d)

 

Your answer is correct.

Not correct. Choice (b) is false.

Try again, this is the point (-2,1.5).

Not correct. Choice (c) is false.

Try again, this is the point (2,-1.5).

Not correct. Choice (d) is false.

Try again, this is the point (-1.5,2).

Question 4

Which set of points are plotted below?

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

 

Not correct. Choice (a) is false.

You have the and coordinates the wrong way around.

Not correct. Choice (b) is false.

You have some correct and some with the and coordinates the wrong way around.

Your answer is correct.

You have all seven points correctly stated.

Not correct. Choice (d) is false.

You have the stated first and second last points incorrectly, they should be (-3,-2) and (3,-1).

Question 5

Consider the equilateral triangle plotted below.

Which one of the following points would be required to add an extra equilateral triangle in the fourth quadrant?

a)		(0,2.35).		b)		(2,-1)
c)				d)		(4,2.35).

 

Not correct. Choice (a) is false.

Try again, you are still in the first quadrant and this is not quite equilateral.

Not correct. Choice (b) is false.

Try again, this gives an isosceles triangle, not equilateral.

Your answer is correct.

The height of the triangle is so we must go down units and

Not correct. Choice (d) is false.

Try again, you are still in the first quadrant and this is not quite equilateral.
