Answer: -4/3
The slope of the given line is 3/4. It's simply the value in front of the x. To be more specific, the equation given to us is in the form y = mx+b where m = 3/4 is the slope.
Flip the fraction and then the sign
flip the fraction: 3/4 ----> 4/3
Then flip the sign: 4/3 ----> -4/3
In other words, we take the negative reciprocal
Notice how the original slope 3/4 and the perpendicular slope -4/3 multiply to -1
Answer:
ANSWER
Let one number = x
other number = 2x-3
(x+2x−3)+7=37
3x = 33
x = 11
∴ The two number are 11 and 19
(5,3) is the answer because it is three units to the right and 5 is 3 away from 2. the distance between is 7, so the makes it a 3:4 ratio.

Answer: C. 12 pouches for $2.80</h3>
Explanation:
x = number of pouches
y = cost for having x number of pouches
To find the unit cost, divide y over x
For choices A through D we have the following unit costs
- y/x = 2.04/8 = 0.255
- y/x = 2.69/10 = 0.269
- y/x = 2.80/12 = 0.233 (approximately)
- y/x = 3.80/16 = 0.2375
We see that 0.233 is the lowest unit cost, so therefore, Choice C is the lowest cost per pouch.
Answer:
x is positive, and y is negative
Step-by-step explanation:
-60° is a fourth-quadrant angle, where x is positive and y is negative.
