Answer:

2. -(-73) is positive

Step-by-step explanation:

It's not too difficult, but you can get wrapped around the axle. Here are the rules:

the opposite of a positive number is a negative number
the opposite of a negative number is a positive number

That is, turning a number to its opposite is just changing its sign.

If you layer these rules, you find ...

the opposite of (the opposite of a positive number) is a positive number

The first rule tells you the statement in parentheses is a negative number, and the second rule tell you its opposite is a positive number.

That is, a double opposite gets you back where you started. In short, any even number of minus signs cancel each other.

The numbers you have listed here* are ...

-730 (negative)
-(-73) = 73 (positive)
-75 (negative)
-(-(-701)) = -701 (negative)

_____

* We say "listed here" because we're seeing mismatched parentheses and brackets, so we know something is missing. We're going by the signs and numbers that we do see. YMMV

Which of the following shows of the slope of the line and one point on the line?

uysha [10]

Answer is choice D

This is the only answer choice with a negative slope, so we don't even need to look at the point really. Though if you wanted, you can confirm that the point (1,-3) is on the diagonal line. This point is shown in red in the attached image.

To find that the slope is -6/5, you pick two points on the diagonal line and use the slope formula. Two points you can use are (1,-3) and (-4,3).
The slope formula is m = (y2-y1)/(x2-x1)

Note: The negative slope is because we move downhill as we move from left to right along the diagonal line.
