Answer:
Parallel
Step-by-step explanation:
• Parallel lines have equal slopes
• The product of the slopes of perpendicular lines is - 1
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 2x - 7 is in this form with slope m = - 2
- y = 2x + 13 ← multiply through by - 1
y = - 2x - 13 ← in slope intercept- form with slope m = - 2
Both lines have the same slope, that is m = - 2, hence
The graphs of the lines are parallel
