So for this one you can look at the change in y over the change in x. If you look on the y part, it keeps changing by 2 so that’s the change in y. And then the change in x is 2 as well
Slope is change in y/change in x
So the slope would be 2/2 which is 1
you can use 1 point to plug into y=mx+b where your m is your slope. So you have
y=1x+b
We can use the point (1,-4)
So we have
-4=1(1)+b
So we have
-4=1+b
And b=-5 so your equation is
y=x-5
I hope this helps!!!
