Question

Determine which of the following line parallel to the line with the equation y=6-x

Answer 1

y = -x + 7

.. lots of possible answers

Explanation:

y=mx+c

c is also known as b

c = b

Same gradient lines are parallel

m = gradient

x = x-axis

y = y-axis

c = y-intercept OR b

y = 6 -x

Rearrange

y = -x + 6

PARALLEL LINE EXAMPLE:

y = -x + 7

.. c can be any number, but gradient must remain
