Solution by Steps
step 2
To determine the correct slope field, we need to analyze the behavior of the slopes based on the equation dydx=x2y\frac{d y}{d x} = \frac{x-2}{y}
step 3
For x>2x > 2, x2y\frac{x-2}{y} is positive if y>0y > 0 and negative if y<0y < 0
step 4
For x<2x < 2, x2y\frac{x-2}{y} is negative if y>0y > 0 and positive if y<0y < 0
step 5
At x=2x = 2, dydx=0\frac{d y}{d x} = 0 for all yy
step 6
Based on these observations, the slopes are positive in the first and third quadrants and negative in the second and fourth quadrants
step 7
The slopes appear to be steeper as the absolute value of xx increases

Key Concept
Slope Field Analysis
Explanation
The slope field of a differential equation dydx=x2y\frac{d y}{d x} = \frac{x-2}{y} shows the behavior of the slopes based on the values of xx and yy. By analyzing the signs and steepness of the slopes in different quadrants, we can match the correct graph.
