If two lines are perpendicular then the product of their gradient is equal to -1
So over here thd gradient of one line is 2 so to find gradient of other line we'll do " 2 × m = -1 "

Den u can go on to solve .....
m = -1/2
c= 10 ( cuz its passing thru (0,10) )
Therefore y=-1/2x + 10
m = -1/2
c= 10 ( cuz its passing thru (0,10) )
Therefore y=-1/2x + 10

the tank i got something like 78? and for m it was 2 and n it was -10. I'm sure of the answer but not of the method.
Will they penalise if i don't use the correct method even if the method is sensible?
