Which value of m will create a system of parallel lines with no solution?<br> y=mx-6<br> 8x-4y=12
Dvinal [7]

Answer: y = 2x - 6

Step-by-step explanation:

   Let us turn the second given equation into slope-intercept form to match the first equation.

8x - 4y = 12

8x - 12 = 4y

4y = 8x - 12

y = 2x - 3

   Now, parallel lines have the same slope. This is the <em>m</em> value.

y = <u>2</u>x - 3

   \/

y = <u>m</u>x - 6

y = 2x - 6
