Answer:
y = 4x -5
Step-by-step explanation:
y = mx+b
m = slope
b = y-intercept
so y= 4x -5
You just need a vector that is perpendicular to the normal vector for your plane. Your normal is <3, 1, -4>. An orthogonal vector is
<4, 0, 3><span>
The plane through the origin with this as it's normal is
4x + 3z = 0</span>
