when x = -3

so for all y's are x = -3 the gradient is 27 which is a friggin big gradient so the line wud almost be vertical.

Do this for all x given.

Plug in the x-values into the derivative to find the gradient at that point

x=-3 , m = 27
x= -2 , m = 12

etc

and you show this on a graph:

its not accurate but yeh

so for x= -3 ,m = 27 yerh

soo the gradient for all values of y in x=-3 is 27
for x=-2 , m = 12 ; so the gradient is always 12 at x=-2
x=0 , m = 0  ; so the gradient is always 0 when x= 0
so you draw it in my last post but more accurate x]

sub x for t and put your mode to differential equations.

This is probably obvious and most likely wont work, but its worth a try as it wont kill you.

Clear A-Z and new prob so settings are all cleared. Define and change settings --> to differential eqns and check all of your mode again.
