Question 1(Multiple Choice Worth 1 points)
(05.02 LC)

Which equation does the graph below represent?

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 20 to positive 20 in increments of 4 for each grid line. A line is shown passing through the ordered pairs negative 4, 16 and 0, 0 and 4, negative 16.

y = fraction 1 over 4x
y = 4x
y = fraction negative 1 over 4x
y = −4x

If you can't tell "by inspection" or by computing the change in y (-16) divided by the change in x (4) as -4, then you can always check to see which of the equations predicts the proper value for y.

1) (1/4)*(-4) = -1, not 16
2) 4*(-4) = -16, not 16
3) (-1/4)*(-4) = 1, not 16
4) -4*(-4) = 16 . . . . as required

The 4th selection is appropriate.
