Best ResponseYou've already chosen the best response.0For the first question, two lines are perpendicular when their slopes are negative reciprocals (that is to say slope1 times slope2 = 1). So if you solve the given (4x+9y=7) line in terms of y, you get: y = (4/9)x(7/9). This means the slope of that line is 4/9. So, the slope of the line you are trying to find would be 9/4. Now use this slope and the given point [(x0,y0)=(6,5)] in the equation yy0=m(xx0) where m is your slope.

Best ResponseYou've already chosen the best response.0Okay that is what I did but i did not use a negative i kept 9/4 positive

Best ResponseYou've already chosen the best response.0Same process for the other two questions. Solve for y in the given equation, the coefficient of your x is your slope, sub that and your given point into the equation yy0=m(xx0) and solve for y again.

Best ResponseYou've already chosen the best response.0Sorry, my mistake. The slope of the given line would be 4/9 so the slope you want to use is 9/4 as you said.
