This keeps on confusing me. Please explain it to me.
9966 [12]

Answer:

x=-10

Step-by-step explanation:

the picture is showing

1+1= -1 + -1 + -1 + -1 + -1 + -1 + -1 + -1 + -x

simplified its:

2= -8 + -x

I think that the answer is x=-10 cuz if u did -8 - -10 then the two negatives make a positive and it makes 2 but idk if the minus sign before the x means minus or negative so this might be the answer but dont blame me if im wrong. I warned you. If its right plz write that.

Answer:

Slope is 3/2

Step-by-step explanation:

If you're going from point (1,4) to point (-3,-2), then your answer slope = -3/2.

If you're going from -3, -2 to 1,4 then it's 3/2 because you are going up 3, over 2 each time.

\frac{rise}{run} = \frac{3}{2}
