what orderd pair lies on the graph of the function of y=-2x+1

Answer 1

You can plug in any value of x and find the corresponding value of y!

I would use x = 0 for simplicity's sake ... y = -2(0) + 1 = 1

meaning that an ordered pair on the line is (0,1)

Answer 2

Here are some choices (note: put x in the equation and calculate y):

Answer 3

There's an infinite amount, but I bet you were given choices.

Remember that a point is (x,y). If your point is (3,2)...

2 = -2(3) + 1

2 = -6 + 1

2 = -5

0 = -7

Since that is not true, (3,2) does not lie on your graph.
