Use patterns or a linear equation to complete the table.

11) x y
1 -1
3 3
5 7
10 ?
50 ?
100 ?

I don't understand what I'm suppose to do! Please hep and explan well! Thank you!

  • Math - ,

    X|Y
    ---
    0|(-3)
    1|-1
    2|(1)
    3|3
    4|(5)
    5|7

    y=2x-3

  • Math - ,

    when x=10, y=17
    when x=50, y=97
    when x=100, y=197

    That is no where near what I need I need help please!

    Thank you(:

    Valerie,
    Read what w said carefully

    y = 2 x - 3 !!!
    for any x, that gives you y
    w noticed that all the given points sat in the straight line y = 2x-3

  • Math - ,

    Now the wayt ot figure that out is to take the slope between any two points
    like here
    m = (7-3)/(5-3) = 4/2 = 2
    so if there is a linear relation
    y = 2 x + b
    now what is b?
    when x = 1, y = -1
    -1 = 2 + b
    so b = -3
    now check to make sure that fits all points, then use it.
