Answer:
Line 1 and Line 2: Neither
Line 1 and Line 3: Perpendicular
Line 2 and Line 3: Neither
Explanation:
6x + 10y = -6
10y = -6 - 6x
y = -6/10 - 6/10x
y = 6/10x - 6/10
y = -3/5x - 3/5
••••••••••••••••••••••••
5y = 3x + 4
y = 3/5x + 4/5
••••••••••••••••••••••••
y = 5/3x - 3
(Already in slope-intercept form)
Once you’ve done that, graph the lines and tell wether they are parallel, perpendicular or none
