used to show the rate of change of a function at a specific set of given points
b. Sketch two possible solution curves for the differential equation.
The slope of each tangent line depends on the x-value.
Solution Curve a possible graph of the differential equation for a given slope field.
1a. Sketch the slope field for x and y in [-3,3] to represent the differential equation
2. This is the slope field for:
.dy
a xdx
. 2dy
b xdx

c ydx
. 2dy
d ydx
. 1dy
e ydx

The slope of each tangent line depends on the y-value.
There are horizontal tangents when y = 0.
Slopes are negative when y’s are negative.
