Answer:
slope = -3/2
Step-by-step explanation:
The slope of a line passing through the two points P=(x1,y1) and Q=(x2,y2) is given by m=y2−y1/x2−x1.
We have that x1=2, y1=5, x2=8, y2=−4.
Plug the given values into the formula for slope: m= (-4)-(5)/ (8)-(2) = -9/6 = -3/2
the slope of the line is m = -3/2
Let us say that:
a = black kittens
b = white kittens
We know that:
a = 5 b
a + b = 25
Therefore:
5 b + b = 25
6 b = 25
b = 4.17
But we cannot have a fraction value for the number of
kittens, so round off:
b = 4
So a is:
a = 25 – 4 = 21

The answer is b 5x-y=7 2x+y=0
