y=7 is just a straight horizonal line that is perpendicular to the y axis at 7and y=1/2x+6, is in y=mx+b form where m=slope and b=yintercept so to find the intersection, yo just find when both sentances are correct so y=7subsitute that into y=1/2x+67=1/2x+6subtract 6 from both sides1=1/2xmultiply both sides by 22=xso the point (2,7) is the intersection
