Acoordinate grid from negative 2 to 0 to positive 2 is drawn. there are three grid lines between a whole unit on the grid. part a: which point represents the origin? part b: starting from the origin, explain how to plot the following three points accurately: (2, −2) (−2, 1.5) (−1, fraction 2 over 4)

Acoordinate grid is shown below: a coordinate grid from negative 2 to 0 to positive 2 is drawn. there are three grid lines between a whole unit on the grid.part a: which point represents the origin? (2 points)the center point (0,0)part b: starting from the origin, explain how to plot the following three points accurately: (1, −1)starting from the origin move right one unit, then down one unit.(−1, 1.25)starting from the origin move left one unit, then up 1.25 units.(−2, fraction 3 over 4)starting from the origin move left two units, then up 0.75 units.(8 points)
