Answer:
Step-by-step explanation:
1. Convert to slope intercept form (y=mx+b)
2. Find slope (the 'm' in mx)
3. Find slope of perpendicular line
So for the first question:
Convert to slope Intercept form if necessary:
3x+4y=12
4y=12-3x<<Subtract by 3x
y=3-3/4x<<Divide by 4
Find slope
y=3-3/4x
3/4 is the slope
Find slope of perpendicular line
To find the slope of a perpendicular line, you just have to take the reciprocal of the original slope and take the opposite sign.
Here is what I mean:
3/4<<original slope
4/3<<reciprocal
-4/3<<opposite
So for the first question -4/3 is the answer.
Now you can do the rest! Hope this helps!
