Geometry Practice Test 2

Question : 34 of 40

Marks: +1, -0

The lines 6x - 4y + 20 = 0 and 3x - 2y - 18 = 0 are mutually—.

Solution:

6x − 4y + 20 = 0
4y = 6x + 20
y =

3/2 x + 5

... (i)
3x − 2y −18 = 0
2y = 3x −18
y =

3/2 x - 9

... (ii)
In both lines (i) and (ii), slope =

3/2

Hence, they are parallel.
