Find the equation of the ine that contains the point (5, - 1) and has slope 1/5.

please help!

  • Algebra 1 -

    We know that

    y = mx + c

    where m is the slope, so the equation we're looking for has to be

    y = (1/5)x + c

    (or y = x/5 + c, which is easier to write n this board!)

    Now all we have to do is find c.

    We know that (5, -1) must satisfy the equation, do to find c:

    y = x/5 + c

    -1 = 5/5 + c

    and I'll leave you to finish it from there.
