not sure how to sketch a slope field...
have u been taught that?
ganeshie8 (ganeshie8):
can you take a screenshot of original table and attach ?
ganeshie8 (ganeshie8):
just draw a small line segment at each point in the table with the corresponding slope value
ganeshie8 (ganeshie8):
keep in mind "slope at a point = dy/dx at that point"

wait what..

whats the value of dy/dx at point (-1, 1) ?
hartnn (hartnn):
ohh!
slope fields are just small line segments with that slope ?
hartnn (hartnn):
at that point
ganeshie8 (ganeshie8):
yes drawing a lot of them gives an almost smooth integral curve
OpenStudy (anonymous):
-1/3

how does a line of slope -1/3 looks like ?
ganeshie8 (ganeshie8):
something like this ? |dw:1420312113700:dw|
ganeshie8 (ganeshie8):
draw that line element at the point (-1, 1)
OpenStudy (anonymous):
yea

not quite, just draw a tiny element staying closer to the point (-1, 1)
OpenStudy (anonymous):
what do you mmean by element i dont get it
OpenStudy (anonymous):
can you show me an example
