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

You can check fairly easily.

Take the first number in the parenthesis. That is what you plug in for x. Then you just see what y is. If it's the same as the second number in the parenthesis, that point is on the line!

As an example, if you had (9,7), you would say
y=-4*9+1
y=-36+1
y=-35

And since 7=/=-35, you know that (9,7) is not on the line.
