Your equation is not complete.

6x + = 9?

Sorry, I'm stressing badly. The equation is (6,7);6x+y=9. Thank you kindly.

(6,7);6x+y=9.

y = mx + b

6x + y = 9

y = -6x + 9

m = -6

m1*m2 = -1

-6*m2 = -1

m2 = 1/6

So, the slope of the perpendicular line is 1/6.

y = 1/6 x + b

Now find b with point (6,7).

y = 1/6 x + b

7 = 1/6 (6) + b

7 = 6/6 + b

7 = 1 + b

b = 6

y = 1/6 x + b

y = 1/6 x + 6
