Which of the following are the correct properties of slope? check all that apply. a. the slope of a line is always positive. b. if two lines have the same slope, then they are the same line. c. a steep line has negative slope. d. the slope of a line that moves up from left to right is positive. e. some lines have an undefined slope.

Using concepts for the equation of a line, the correct options are:

D.The slope of a line that moves up from left to right is positive.

E.Some lines have an undefined slope.

-------------------------------

The equation of a line is given by:

In which m is the slope and b is the y-intercept.

Among the properties of the slope, there are:
