Answer: The slope of line c is given by
Step-by-step explanation: Given that line b is perpendicular to line a and line c is perpendicular to line a.
We are to find the slope of line c.
From the graph, we see that (2, 3) and (-3, -2) are two points on the line b.
We know that
the slope of a line passing through the points (p, q) and (r, s) is given by
Therefore, the slope of line b will be
Since lines a and b are perpendicular, and the product of the slopes of two perpendicular lines is -1, so we must have
Again, lines c and a are perpendicular, so
Therefore, the slope of line c is given by
