3y = x - 6
y = 1/3x - 2.
slope her is 1/3. A perpendicular line will have anegative reciprocal slope. To find the negative reciprocal of a number, u flip the number and change the sign. So the slope we need os -3/1 or just -3.(see how I flipped the slope and changed the sign)
y = mx + b
slope(m) = -3
(3,-5)...x = 3 and y = -5
now we sub and find b, the y int
-5 = -3(3) + b
-5 = -9 + b
-5 + 9 = b
4 = b
so ur perpendicular equation is : y = -3x + 4

Answer:
I think it is triangular prisim
Answer: 
Step-by-step explanation:

Since our ''y'' is already isolated, you can simply plug ''y'' information into the second equation.

Now we can use the first equation and replace ''x'' to find ''y''

To prove that your values are correct, take any of the equations and replace their values.

Answer:
The answer is $4.10
Step-by-step explanation:
If 3 pounds = $1.23
1 pound =1.23/3
= 0.41
Therfore 10 pounds = 10× 0.41 = $4.10
