Ok a few questions I want to check answers on -
-x+4-9x+3¡Ý 7(x-2)
-10x+7¡Ý7x-14
-10x-7x¡Ý7x-7x-14
-17x¡Ý-21
-17x/-17¡Ý-21/-17
x¡Ý21/17 or x¡Ü21/17 ??

One I do not understand at all -
The linear equation y=3x-5 graphs as a horizontal/vertical/diagonal line)choose the correct label)
Is it asking for a answer of horizontal, vertical or diagonal?

Finally
Name the coordinate described here:
From the origin, the point is six places to the right and five places up.
(6,5) 6 is the x-coordinate and 5 is the y-coordinate
Is that the answer the question is looking for?

Thanks for help.

    Ok my first question messed up as I do not know how to type a greaterthen/equal sign and lessthen/equal sign.
    so it should be
    -x+4-9x+3 >= 7(x-2)
    -10x+7 >= 7x-14
    -10x-7x >= 7x-7x-14
    -17x >= -21
    -17x/-17 >= -21/-17
    x >= 21/17 or x <= 21/17 ??

    The correct answer is x ≤ 21/7

    When you divide (or multiply) by a negative number, which you did in your second-last line, you have to reverse the inequality sign.

    BTW. to get the ≤ sign,
    hold down the Alt key, at the same time press 243 on the number pad, then release the Alt key.

    try it also with 241,251 and some other values. REAL COOL

    For "The linear equation y=3x-5 graphs as a horizontal/vertical/diagonal line)choose the correct label)
    Is it asking for a answer of horizontal, vertical or diagonal? " it sounds like they want you to choose one of the tree labels.
    Since the line has a slope of 3, it can't be either horizontal nor vertical.
    It is a "diagonal" line.

    For the last one, you are right.
    It is as simple as it appears.
