Graph the line with slope 2 passing through the point (-5,4)

  • Math - ,

    for a second point, you know y goes up 2 for every x. So add 6 to x, y should increase by 12. (1,16)

  • Math - ,

    I don't get it!!

  • Math - ,

    Here is another way to think about it.

    You could write the equation of the line first in y = mx+b
    You substitue:
    4 = 2(-5) + b
    4 +10 = b
    14 = b

    y = 2x + 14

    Now let x = some values and solve for y and you will have the points you need to graph the line.
