It would be a negative or positive depending on the situation.
Step-by-step explanation:
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.
Use the formula slope= y-y/x-x -10-r/-2-8= 1/10 -10-r/-10= 1/10 Multiply the denominator (-10) on both sides -10-r= -1 Add -10 to both sides -r= 9 r= -9 Hope this helps!
