Answer:
2x-y = 1
Step-by-step explanation:
Equation of the line is y-y1 = m (x-x1), where m is the slope and (x1,y1) is a point that lies on the line.
Equation of the given line is,
y-(-1) = 2 *(x-0)
y+1 = 2x
2x-y = 1
Answer
x=63
y=18
explanation
x+y=81
2x=7y
solve for x
x=(7/2)y
sub into first equation
(7/2)y+y=81
(9/2)y=81
y=18
sub into x equation
x=(7/2)(18)
x=63
