Answer:
5x-6y-12=0
Step-by-step explanation:
...make y the subject y=-6/5x +2
...use the coefficient of x as the gradient,m=-6/5
...for a perpendicular line,find the negative reciprocal of the gradient,5/6
...sub into the eqn y= -1/m(x-a)+b
kilometers and miles are units used to measure distance.
1 mile is equal to 1.61 km
so if 1 mile is equivalent to 1.61 km
then to see how many kilometers are there in 50 miles we have to multiply 50 miles by 1.61 km/mile
therefore the number of km in miles is - 50 miles x 1.61 km/mile = 80.5 km
distance in km - 80.5 km
