Ok a few questions I want to check answers on 
x+49x+3¡Ý 7(x2)
10x+7¡Ý7x14
10x7x¡Ý7x7x14
17x¡Ý21
17x/17¡Ý21/17
x¡Ý21/17 or x¡Ü21/17 ??
One I do not understand at all 
The linear equation y=3x5 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 xcoordinate and 5 is the ycoordinate
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+49x+3 >= 7(x2)
10x+7 >= 7x14
10x7x >= 7x7x14
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 secondlast 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=3x5 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.
