Answer:
Option (C)
Step-by-step explanation:
a). Slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is represented by the expression,
Slope = [tex]\frac{\text{Change in y-coordinates}}{\text{Change in x-coordinates}}[/tex] Or [tex]\frac{\text{Rise}}{\text{Run}}[/tex]
= [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
= [tex]\frac{\triangle y}{\triangle x}[/tex]
Therefore, slope ration of a linear function is represented by [tex]\frac{\triangle y}{\triangle x}[/tex]
Hence, Option (C) will be the correct option.
