If line b is perpendicular to line a, and line cis perpendicular to line a, what is the slope of line c?

m = 1

Step-by-step explanation:

Lines b and c are parallel and thus have the same slope.  We need only find the slope of b or the slope of c, and will then have both.

                                        5

The slope of b is m =  =  1

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

only 2 outcomes have passed the given condition.
