easy technique for this format of problem
swap the coefficients ... 2y - 5x = ?
change one sign ... 2y + 5x = ?
plug in point ... 2(7) + 5(-2) = 14 - 10 = 4
equation is ... 2y + 5x = 4
Find an equation of the line that is perpendicular to the line whose equation is 2x – 5y = 3 and passes through (-2, 7).
