Answer:
waterfall 5 percent
ravine 30
creek 15percent
cabin 20
hill 5 percent
bluff 10
ravin 25 percent
probability is 98 percent
The first thing to do with these problems is to convert them into y=mx+b form; this will literally show you the answer to slope and y intercept since m=slope and b=y intercept.
To convert, isolate the y and the rest should fall into place. Subtract 2x from 4y and the other side of the equation to get the equation 4y= -2x+9 (put the x first because of mx+b). Then Divide the 4 from y and do the same to the other side to get y= -1/2x+9/4. M= -1/2 so that is the slope. B=9/4 so that is the y intercept
The answer would be C because the middle point, which is F should be in the middle when naming the angle
Answer x=-14.
