/ -1

Step-by-step explanation:

so to find slope, the equation for it is (or it can be , but in this instance i used the   formula.) it can be simplified like if it was any fraction. Well, i mean, it kinda is, but thats not the point.

anyways, you would start at (2,1) and "rise" up until its in the same line as (-2,3), which would be 4. so your rise would be 4.

Now, since the next value is negative, instead of "running" to the right, we would "run" to the left until you reached the next point (-2,3), which would be -4.

now theres two ways you can write this, which is ,or you can write it in its simplest form which is -1.

i hope this helped :)
