Hi
*[tex \large\ Using \ the \ standard \ slope-intercept \ form \ for \ an \ equation \ of \ a  \ line \ y = mx + b ] 
*[tex \LARGE\ where \ m \ is \ the \ slope \ and \ b \ the \ y-intercept]
x + 7 = y   |slope m = 1  and  y-intercept is Pt(0,7)
y-x=-3 OR y = x - 3   |slope m = 1  and  y-intercept is Pt(0,-3 )
Lines are parallel as each with slope m = 1
