If the 3 points are collinear, then the slopes of all line segments connecting the points are the same.
Thus,
-6 - (-8) 2
m = ------------- = -------- = -1/2
-7 - (-3) -4
Then the following must be true:
4-(-6) 10
-1/2 = ------------ = ---------
c - (-7) c + 7
Cross multiplying, -(c+7) = 20, and c+7 = -20, so that c = -27
Step-by-step explanation:
Can't be rationalize because it will be given us same equation
Fred walked 10 meters down and 24 to the right. You can think of these two segments as the legs of a right triangle.
The hypotenuse of this triangle is the path Fred would have walked through the pond. So, this distance is

So, instead of walking 10+24=34 meters, he could have walked 26 meters, saving 34-26=8 meters.
55 is a rational number because it can be expressed as the quotient of two integers: 55 ÷ 1.
