Step-by-step explanation: 245 x 12= 2,940
When a line is given in the form
The slope of the line is m. So, in this case, the slope of is 1.
Given a slope , you find the slope of a perpendicular line by imposing
So, if the given line has slope 1, a perpendicular line has slope given by
and thus
So, we want a line with slope -1 and passing through (12,-1). Using the fomula
we get
