3x+4y=12
4y = - 3x + 12
y = -3/4 x + 3; This line has slope equal - 3/4
Perpendicular lines, slope is opposite and reciprocal so slope of new line = 4/3
Passing point (6 , -2)
y + 2 = 4/3(x - 6)
y + 2 = 4/3 x - 8
y = 4/3 x - 10
Answer
Equation: y = 4/3 x - 10
You can say 8/10 = 80/100 ⇒ 80/100 is bigger than 79/100 :)))

Recognize that parallel lines have the same slope. Then:
Method 1: write y = 2x + c and find c from the given information:
y = 2x + c becomes 0 = 2(-2) + c, so that c = 4. Then y = 2x + 4 (answer)
Method 2: Slope is 2 and a point on the line is (-2,0):
Use the point-slope formula: y - 0 = 2(x+2), or y = 2(x+2), or y=2x+4 (ans)
