Question

Part A: Which point represents the origin? (2 points)
Part B: Starting from the origin, explain how to plot the following three points accurately:
(1, −1)
(−1, 1.25)
(−2, fraction 3 over 4 )
(8 points)
Your answer:

Answer 1

Step-by-step explanation:

(0,0) represents the origin.

For plotting (1, -1): Firstly move 1 unit from origin on X-axis along positive direction of X-axis. Then from that point move one unit below X-axis parallel to Y-axis.

For plotting,(-1 , 1.25): Firstly move 1 unit from the origin on the X-axis in negative direction. Then move 1.25 units above the X-axis parallel to Y-axis.

For plotting (-2, 3/4): Firstly move from the origin towards left on X-axis. Then move 3/4 units above the X-axis parallel to Y-axis.
