4. Which equation has (2, −1) as a solution? (1 point)

y = 2x − 1
y = x + 3
y = x – 3
y = −2x + 1

1 answer

did you try substituting the given point into each equation?
I'll try the last equation, you do the others

for (2, −1)
LS = -1
RS = −2(2) + 1
= -4+1 = -3 ≠ LS
I guess that's not the one, ....
