    Hi, i can normally do linear programming on D1 quite well however this question is really confusing me.

    Here is the question:

    The answer I got for the top constraint was x = 2y + 15, but the actual answer is x = 2y + 30 (The sign should be greater than or equal to but idk how to put that in)

    Thanks!

    edit: added more info

    Equation for a line is y=mx+c, where m is the gradient and c is the y-intercept.

    The gradient is 1/2, and the y-intercept is 15, so the equation of the line is:

    y=\frac{1}{2}x + 15

    2y = x +30

    Ah of course I should have noticed that, thank you!

    so would they be y < 1/2 x + 15 and y > 1/4 x?

    I'd think you want <= and >=, but other than that, yes.
