Now attempt the questions below. 1. Write down the letter that corresponds to these coordinates on the picture below: a) (3, 2) b) (-2, 4) c) (3, 4) d) (2, -1) e) (0, 3)

 2. Using the picture above, write down the points: a) with a //y// coordinate of 2 b) with an //x// coordinate of -3

3. Use the number plane from the example to help you calculate the distance between the points below:  a) (2, 0) and (5, 0) b) (0, 1) and (0, 4) c) (-1, 0) and (1, 0) d) (0, -3) and (0, 1) e) (-5, 0) and (-1, 0) f) (0, -4) and (0, -2) g) (3, 0) and (-1, 0) h) (2, 0) and (-2, 0) i) (0, 5) and (0, -2)

4. Write down the letter naming the points in the picture below: a) (-1.2, -1.6) b) (3.4, -1.2) c) (1.4, -2.6) d) (2.4, -1.8)

 5. Write down the coordinates of these letters in the above picture: a) //C// b) //A// c) //E// d) //D//

6. Write down the coordinates of the points //A//, //B//, //C// and //D// on each of the following lines:  Try the activity from the website below. Compare your time with the person sitting next to you. Billy Bug and his All New Quest For Grub
