Question 136162
What is the slope of the line {{{y=x}}} ??? remember {{{y = mx +b}}} form of a line? so that slope is 1

What do you know about the slope of parallel lines? The slope of parallel lines are equal. So the slope of the line we are looking for is 1.

Now use the point/slope format for a line to find the second line.
{{{(y - Y) = m(x -X)}}}
{{{(y - 4) = 1*(x - 2)}}}
{{{(y - 4 ) = (x - 2)}}}
{{{y = x + 2}}}
