Does anyone know the Formula for Slopes?

Question

Is it m= y-y
--------
x-x ????

Answer 1

y2-y1
-------- = m(slope)
x2-x1

Answer 2

Paige has it right. the subscripts tell you WHICH y coordinate and which x coordinate. the hard part is not subtracting backwards in one half of the fraction.

If you have 2 points: (-3,4) and (2,-3), you might think of it as a journey from 4 downto -3, -7, as change in y, and a journey from -3 up to 2, +5, as change in x, so slope is -7/5. It takes practice. Beginners want to look at 4 and -3 and write 1, at -3 and 2 and write -1.

Answer 3

Its (y2-y1) / (x2-x1).
y=mx+b is slope intercept form with m being the slope and be being the y-intercept

Answer 4

yes but it's not just (y - y) / (x - x)

the formula is m = (y2 - y1) / (x2 - x1)

y2 means y value of the second point
x2 means x value of the second point

y1 means y value of the first point
x1 means x value of the first point

Answer 5

1. Slope formula: m = [second y - first y]/[second x - first x]

Answer 6

y= mx+b scientific
y-y1=m(x-X1) point slope

Answer 7

first u gotta have ur two vertices for example (5,13) and (2,15)
then..... remember it's alwaizz (x,y)
(5[x1], 13[y1]) and (2[x2], 15[y2]) OR
(5[x2], 13[y2]) and (2[x1], 15[y1])

........................y2-y1
m (slope) = -------------
........................x2-x1

plug the values dat i gave as an example

........15-13
m= -----------
..........2-5

m= 2/-3

Answer 8

Y2-Y1/X2-X1, I believe. hope this helps!!

Answer 9

y2-y1 / x2-x1 or rise orver run

Answer 10

y sub one minus y sub two over x sub one minus x sub 2

y1-y2
--------
x1-x2
