Question 175146
Rewrite both equations into slope intercept form.

1.x+4=y
y-x=-3

y=x+4 (line #1)

y=x-3 )line #2)

What is the slope of each line?

The slope of line 1 is 1

The slope of line 2 is 1.

Yes, the line are parallel.

Here is a graph of the two lines.

{{{graph(300,300,-10,10,-10,10,x+4,x-3)}}}

The lines differ because of different y-intercepts.

I hope that this helps.
