The general point-slope form for a line is #color(white)("XXXX")##y-b = m(x-a)# with a slope of #m# through a point #(a,b)#
#y=3+2(x-1)# can be easily converted into that form: #color(white)("XXXX")##y-3=2(x-1)# #color(white)("XXXX")##color(white)("XXXX")#with a slope of #2# through the point #(1,3)#
