Answer:
It would be a negative or positive depending on the situation.

A negative minus a negative would result in either a positive or negative. For example, -8 - (-9) would be 1 while -8 - (-7) would be -1. If the negative number your subtracting is greater than the number you're subtracting from then it will be positive, vice versa.
Answer:
64
Step-by-step explanation:
G=4ca-3ba <=> G=a(4c-3b)
<=> a=G/(4c-3b)
The point-slope form:

We have the points (5, -3) and (-2, 9). Substitute:

Answer:
No
Step-by-step explanation:
x = -2 represents a vertical line that intersects the x axis at the point (-2, 0). Since the line is vertical, the slope is undefined making it not have a positive slope.
Best of Luck!
