    If y = A and y = B, then set A = B, solve for the X value

    the point (3,5) is where the two lines intersect

    so y = 5 means that our x is set at 0 so draw a horizontal line at (0,5)

    hmmm... if we're going to use the graphing method we have to graph y = 5 which is a horizontal line. Since x isn't given, it's already 0. so we have a horizontal line at (0,5) then for y=3x-4 we let x = 0,1,2,3... and solve for y to get points. we then use that information to graph until we find the point of intersection with is (3,5)

    it is supposed to be (3,5) that's the point of intersection.... but since it's the graphing method instead of substitution method then we graph 2 lines.

    I don't think so.. when we did y =3x-4 we let x be any number we choose until we find the point which draws the line further to intersecting the other line. In this case when our x =3, our y = 5 since we have a horizontal line y =5 that point (3,5) from y =3x-4 crossed the horizontal line y = 5

    as soon as we reach a certain x value that produces a point of intersection, we're done. If we have perpendicular lines (two lines that intersect) that means that there is one solution. 2 parallel lines means no solution.

    is that for graphing y = 5 only? then yes it's (0,5) on the x-axis it's 0.. so x = 0 and y = 5 at point (0,5) the horizontal line is drawn
