Answer:
m=3
Step-by-step explanation:
To get a perpendicular equation to another equation, the slope must be the reciprocal of it.
First, you need to isolate the y variable so you can identify the slope.
12y = 8 - 4x
Divide both sides by 12 (and for me I like to keep x close to y).
[tex]y=-1/3x+2/3[/tex]
Now that we have converted it to y=mx+b, we can compare. The reciprocal of 1/3 is 3.
so m = 3.
