no point M provided.
But just take the (x,y) values of M and see whether they satisfy each equation.
Heck, try each one twice, since you insist on repeating everything!
Which two equations is Point M the solution to?
y=−3x+1y is equal to negative 3 x plus 1
y=2xy is equal to 2 x
y=12x − 1y=12x − 1
y=−x+2
2 answers
y=1/2x-1
y=-3x+1
y=-3x+1
