Question

A coordinate 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?

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)

Answer 1

Answer:

Part A: (0,0)

Part B:

(1, -1) go over one to the right and down one

(-1, 1.25) go over one to the left and up 1.25

(-2, 3/4) go over two to the left and up .75

Step-by-step explanation:

Part A: the origin of a graph is always (0,0)

Part B:

(x, y) the first number is your x which goes left and right. if the number is negative you go left and if the number is positive you go right. the second number is your y which goes up and down. if the number is negative you go down and if the number is positive you go up

Answer 2

part a: the point 0,0 represents the origin
