point slope form is y-y1=m(x-x1)
where the slope is m and a point on the line is (x1,y1)
so
slope bewteen (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1)
slope bewteen points (-1,-2) and (-2,-6) is
(-6-(-2))/(-2-(-1))=(-6+2)/(-2+1)=-4/-1=4
pick either (-1,-2) or (-2,-6)
I pick (-1,-2)
slpoe is 4
y-(-2)=4(x-(-1))
y+2=4(x+1)
