Question

the line that is described by the equation y=-4x+1 contains which of the following?
A) (0,1)
B) (-3,1)
C) (1,3)
D) (-2,-3)

Answer 1

Its simple really,
Just apply one of the co-ordinates and check if the other one is the answer you get.
As in let us take the first co-ordinates. A)(0,1)
Let us apply x=0 in the equation in y=-4x+1
\[y=-4(0)+1\]\[y=1\]
This satisfies the equation, So A is your answer.
