Question 58314
Determine which two equations represent parallel lines.(a)  y =  x + 3	(b)  y = x – 6	(c)  y = 2x + 10	(d)  y = 2x – 3
These equations are in slope intercept form:{{{highlight(y=mx+b)}}}, m=slope, and b=y-intercept.
Parallel lines have the same slopes.
(a)y=(1)x+3
(b)y=(1)x-6
(a) and (b) both have a slope of 1 and are parallel.
:
(c) y=(2)x+10
(d y=(2)x-3
(c) and (d) both have a slope of 2 and are parallel.
