The slope is 1

Explanation:

Given:" " x-y+1=0 xy+1=0

Add yy to both sides giving

x-y+y+1=0+yxy+y+1=0+y

x+0+1=yx+0+1=y

y=x+1y=x+1

Although not normally written this way I am going to show you.

There are 1 of xx so you could write

y=1x+1y=1x+1

The 1" from "1x1 from 1x is the gradient (slope)

This means that for 1 along you go up 1
