Which equation does the graph below represent? (5 points)
A coordinate grid is shown. The x axis values are from negative 5 to positive 5 in increments of 1 for each grid line, and the y axis values are from negative 10 to positive 10 in increments of 2 for each grid line. A line is shown passing through the ordered pairs negative 4, negative 8 and 0, 0 and 4, 8.
y = 2x
y = fraction 1 over 2x
y = fraction 1 over 2
y = 2 + x
