The Slope Field for the Differential Equation $\frac { d y } { d x } = - \frac { x } { y }$

Multiple Choice

The slope field for the differential equation $\frac { d y } { d x } = - \frac { x } { y }$ is shown below.If you start from the point $( 0 , - 2 )$ and use Euler's method with N = 3 subdivisions to approximate the value of y when x = 1, is your answer an underestimate or overestimate?

A) An overestimate
B) An underestimate
