The equation of the line has the form: y = ax+b parallel to the line y = -2x + 7
=> a= -2
Passes through (4,1) => x=4, y=1
Substituting into the equation:
1= -2x(4) + b => b= 9
=> y= -2x + 9
A would be 12. If your sister is 6 years older than your brother your brother is 4
if your brother is 1/3 your age 4 times 3 you are 12
I graphed it out and it seems that both A and C are correct. I would check them to make sure.
