Respuesta :

M is the slope. - X is an independent variable. Y is a dependent variable. B is the where the line crosses the Y-axis.

Answer:

Option (c) is correct.

The slope of a line is represented by the variable 'm'

Step-by-step explanation:

Given : The slope a line

We have to choose which variable is used to represent the slope of a line.

Since, the general equation of line is represented by the equation

y = mx + c ,

where m is slope

and c is y intercept.

So , we represent the slope of line by the variable 'm'

Thus, The slope of a line is represented by the variable 'm'
