Answer:
The second option
Step-by-step explanation:
Here, we need to multiply each part of the matrix by -10.
This will give us: [ -230 380 ]
[ -170 60 ]
So, the answer is the second option.
Slope is rise/run or y2-y1/x2-x1. So to find the slope, find two points where the point is exact, then do the equation. That's the best I can explain, sorry if this doesn't help at all.
The answer is 2 and over it is 3
A=7 is what I got since this was a equation problem
OMG I HAD THIS EXACT HOMEWORK LAST YEAR CREEPYYYYY!!!!
A is proportional
B is not
C is proportional I think
