( 2 , - 1 )
mean x = 2 , y = - 1
for
A.
y = 2 x - 1
y = 2 ∙ 2 - 1 = 4 - 1 = 3
for
B.
y = x + 3 = 2 + 3 = 5
for
C.
y = x - 3 = 2 - 3 = - 1
for
D.
y = ( - 2 x ) + 1 = ( - 2 ∙ 2 ) + 1 = - 4 + 1 = - 3
Only equation C
y = x - 3
has solution
x = 2 , y = - 1
OR
( 2 , -1)
which equation has (2 -1) as a solution?
A.y=2x - 1...
B.y=x + 3
C.y=x - 3
D.y=(-2x) + 1
