How do i turn two points into slope intercept form

You use those points and first find the sloope. so change in y over change in x

then once you find the slope. you plug in the points into y=mx+b
ex: if you figured out that m=1 (the slope)
then y= 1x +b..so then say you know that one point is 1,1
so 1=1(1)+b so then b =1
hope this helps
