Which ordered pair is a solution to the system of linear equations 1/2x - 3/4y = 11/60 and 2/5x + 1/6y =3/10 ? A. ( 1/5, -2/3 )

B. ( 1/5, 2/3 )

C. ( 2/3, -1/5 )

D. ( 2/3, 1/5 )

D

Step-by-step explanation:

i multiplied the first equation by 60 to eliminate the fractions: 30x - 45y = 11

i multiplied the second equation by 30 to eliminate the fractions: 12x + 5y = 9

I graphed them and (2/3, 1/5) is the intersection of both lines

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
