1.)rise/run
2.)vertical change/horizontal change
3.)y^2-y^1/y^2-x (x^2=x) [theres a cross throught the equal sign]
4.)x^2-x/y^2-y^1(y^2=y^1) [theres a cross throught the equal sign]

Slope formula
m = y₂- y₁/ x₂- x₁
y₂- y₁= Rise (Vertical change)
x₂- x₁= Run (Horizontal Change)

1 , 2 , 3 are correct because :
raise = vertical change = y2-y1( y2 not y power 2 )
run = horizontal change = x2-x1
and slope is said to be differece of y / differnce of x
number 4 is wrong it says diff of x / diff of y
so the wrong answer is sure number 4

4.
x is the horizontal run, not the vertical rise.
the definition of slope is rise over run or y/x
