Answer:
Slope in fraction form = 5/2
Slope in decimal form = 2.5
========================================================
Work Shown:
m = (y2-y1)/(x2-x1)
m = (-5-10)/(-2-4)
m = (-15)/(-6)
m = (-3*5)/(-3*2)
m = 5/2 slope in fraction form
m = 2.5 slope in decimal form
-----------------
Explanation:
The first step is the slope formula where (x1,y1) and (x2,y2) are the two points the line goes through.
I used (x1,y1) = (4,10) and (x2,y2) = (-2,-5)
The slope formula basically says "subtract the y values, then subtract the x values in the same order. Then divide the two differences".
Or you can think of it as
slope = rise/run
rise = y2-y1 = change in y
run = x2-x1 = change in x
Answer:
when you evaluate a number if it is positive do nothing if it is negative switch it to a positiive sooo 12 4 and 8 :)
Step-by-step explanation:
2x -4xydy/dx+ 2ydy/dx= 0
(2y-4xy) dy/dx = -2x
dy/dx = -2x / 2y-4xy
