Use the coordinate grid to determine the coordinates of point a: coordinate grid shown from negative 2 to positive 2 on x axis and negative 2 to positive 2 on y axis. there are increments of 1 over 4 for each grid line on each of the two axes. only the whole numbers are labeled on either side of the axis. a point a is shown at the intersection of 5 grid lines to the left of the y-axis and 3 grid lines above the x-axis. what are the coordinates of point a? ( fraction negative 1 and 1 over 4, fraction 3 over 4) ( fraction 1 and 1 over 4, fraction negative 3 over 4) ( fraction negative 3 over 4, fraction 1 and 1 over 4) ( fraction 3 over 4, fraction negative 1 and 1 over 4)
