Passing through point (1,4); perpendicular to
How do I solve this? I think it might be this but not sure please let me know what step I left out



  • college algebra -

    from y = 5 - 2x
    y = -2x + 5 , (why did you switch the signs in yours ???)
    the slope is -2

    so the slope of the new line is 1/2

    y = (1/2)x + b
    sub in the point (4,1)
    4 = (1/2)(1) + b
    4 - 1/2 = b
    b = 7/2

    new equation is
    y = (1/2)x + 7/2
