Find an equation of the line that is perpendicular to the line whose equation is 2x – 5y = 3 and passes through (-2, 7).

    Easiest way:

    An equation perpendicular to 2x - 5y = 3
    must have the form
    5x + 2y = c

    plug in our given point on this line:
    5(-2) + 2(7) = c = 4

    5x + 2y = 4
