Question

write the equation of a parallel to the given line and passing through the given point. y=-x+7; (7,1) I need the answer now please

Answer 1

Parallel lines have the same slope.  Since our reference line has a slope of -1, so will a line parallel to it.  Thus far we have:

y=-x+b, using point (7,1) we can solve for b

1=-7+b

8=b  so the parallel line passing through (7,1) is:

y=-x+8
