If you multiply a negative by a negative is it a positive?
Yes, any time you multiply a negative by a negative, it automatically becomes a positive.
When you add a negative number by a negative number do you get a negative or positive number?
You get a positive number because a negative number reverses the other negative so it becomes a positive number.
What will happen to the slope of a line if the line is shifted so that the y intercept increases and the x intercept remains the same?
The answer depends on the signs of the original intercepts.x negative, y negative: negative slope becomes less negative and could go positive.x negative, y positive: positive slope becomes greater.x positive, y negative: positive slope becomes less positive and could go negative.x positive, y positive: negative slope becomes more negative.For 1 and 3, the slope changes sign when the y intercept crosses the origin.
What does it mean for a negative to be decreased by a negative?
It becomes less negative To explain. Lets take a negative, eg -5. If we decrease it by 1, it becomes -6 (where 1 is positive) Thus if we decrease it by -1, it becomes -4 (as the -1 is negative) Note that the final number could be positive, For example, if you decrease -5 by -6, you get +1
Are all whole numbers positive or negative?
All integers can be positive or negative, including zero. But zero on its own is neither positive nor negative. It is directly inbetween where one becomes the other.
