Hi,

Which of the following ordered pairs is on the graph that represents

 y = 2x-1

Note: an ordered pair(x,y) the 1st number is the x-value and 2nd the y-value

Substitute the values into y = 2x - 1 to determine if that ordered pair

would represent a point on the line:

 y = 2x - 1

-5 = 2*-2 - 1        A.Ordered pair (-2,-5) is on this line

-7 ≠ 2*-4 - 1  B.  NO

 1 ≠ 2*0 - 1   C.  NO

 4 ≠ 2*3 - 1   D.  NO
