Step-by-step explanation:
Given,
a line passes through the point (6,14) and is parallel to the line y =-x-1.
The slope of the given line is -1. [ the coefficient of x]
Since the required line parallel to the given line.
So, the slope of required line is = -1
The equation of line which passes through the point [tex](x_1,y_1)[/tex] and slope is m is [tex]y-y_1=m(x-x_1)[/tex]
Therefore the equation of the required line is
[tex]y - 14= -1(x-6)[/tex]
[tex]\Leftrightarrow y -14 = -x+6[/tex]
[tex]\Leftrightarrow x+y= 20[/tex]
