Step-by-step explanation:
The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.
Parallel lines have the same gradient. Hence the gradient of line r is .
Susbt. m=,
To find c, substitute a coordinate.
When x=3, y= -9,
-9= 1 +c
c= -9-1
c= -10
Thus the equation of line r is .
