The answer is D. I hope this helps love! :)
Perpendicular lines have opposite reciprocals from the original line.
Original line: y=-3/4x+6
Perpendicular line: y=4/3x+b
Solve for b by plugging in the given coordinates (3,9) for x and y respectively.
9=4/3(3)+b
Multiply 4/3*3.
9=4+b
Subtract 4 from both sides.
5=b
Now, with b and the slope, you can write the equation:
y=4/3x+5
I hope this helps :)
Answer:
D
Step-by-step explanation:
Two lines are perpendicular when the product of their slopes = - 1
line 1: y = 3x + 4
(3 , 0) ; (-3,2)
Slope of line 1 = 3
Slope of line 2 = -1/3
3* -1/3 = -1
Assuming you mean (8^2)^-4
This would give is 8^-8 = 1/(8^8)
Which is equal to <span>1 over 8 times 8 times 8 times 8 times 8 times 8 times 8 times 8
The answer is C.</span>
