Answer:
lines are perpendicular
Step-by-step explanation:
• Parallel lines have equal slopes
• The product of the slopes of perpendicular lines = - 1
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange the given equations into this form and extract the slope
3x - 2y = - 6 ( subtract 3x from both sides )
- 2y = - 3x - 6 ( divide through by - 2 )
y = x + 3 ← in slope- intercept form
with slope m =
----------------------------------
4x + 6y = 2 ( subtract 4x from both sides )
6y = - 4x + 2 ( divide through by 6 )
y = - x + , that is
y = - x + ← in slope- intercept form
with slope m = -
--------------------------------------
≠ - , then lines are not parallel
× - = - 1
Thus the lines are perpendicular to each other

Answer:
a
Step-by-step explanation:44
4/5.
___
Steps: Find a common denominator - 20. 4 x 5 = 20 3 x 5 = 15 --- 15/20
5 x 4 = 15 -- 4 x 4 =12 ---- 16/20
16/20 is bigger than 15/20.
So, 4/5 is bigger.
