    What is true about the y co-ordinate of any point on the x axis? Sketch it if you wish, once you know this then work out how to solve this question.

    y has a special value on the x axis ? use this special value in the equation of the line to find x.

    >meets the x-axis at R
    if line meets x-axis at R, then y must = 0
    therefore, let y = 0

    3x+2(0)-5=0
    3x-5=0
    3x=5
    x=5/3

    co-ordinates R(5/3, 0)
