to find a perpendicular line , swap the x and y coefficients and change one of their signs

3x - 2y = 7 is perpendicular to 2x + 3y = 7

the y-intercept (when x=0) of 5x + 2y = 10 is 5 , coordinates (0,5)

plug the coordinates into the new equation to get the proper y-intercept

3(0) - 2(5) = -10

the correct equation is ___ 3x - 2y = -10
