Re-write 2x - 3y >_ 6 in slope- intercept format.
its an equal or greater than sign by the way. Can someone help me? I can't figure out how.

  1. 2x - 3y ≥ 6
    -3y ≥ -2x + 6
    divide by -3, which means we have to reverse the inequality sign
    y ≤ (2/3)x - 2

    which represents the region below the line y = (2/3)x - 2, including all points
    on the line itself.

  2. recall that the slope-intercept format is y = mx+b
    So, you need to get y all alone on the left.
    2x - 3y >= 6
    3y <= 2x + 6
    y <= 2/3 x + 2
    generally, slope-intercept form is used for lines (equations), not inequalities ...
