Question

The line parallel to y = −x that passes through (5, 5.5). The equation of the line that passes through (5, 5.5) is y =

Answer 1

The line parallel to y = -x has the same slope, which is -1, because parallel lines have the same slope.

So you plug 5 and 5.5 into the equation y = -x + b.

5.5 = -5 + b

Add 5 to both sides.

10.5 = b

So, y = -x + 10.5
