Answer:
rise over run
Explanation:
rise refers to the number of units going u or down a graph
run refers to the number of units going left or right
it is seen as so; [tex]\frac{rise}{run}[/tex] , [tex]\frac{ delta y}{deltax}[/tex] , or [tex]\frac{y_{2} - y_{1}}{x_{2} - x{1}}[/tex]
Don't panic when I included "delta". Delta, it refers/means the small mathematical triangle found beside the rise and run symbols of y and x
