She can give 15 cookies to 5 people.
15x5=75
75 is less than 100, so she can give out cookies and still have 25 left over.
X + 5y = 14
5y = -x + 14
y = -1/5x + 14/5.....the slope here is -1/5. A perpendicular line will have a negative reciprocal slope. All that means is flip the slope and change the sign. So our perpendicular slope will be 5. See how I flipped -1/5 making it -5/1...and then changed the sign, making it 5.
y = mx + b
slope(m) = 5
(-5,-2)....x = -5 and y = -2
now we sub and find b, the y int
-2 = 5(-5) + b
-2 = -25 + b
-2 + 25 = b
23 = b
so ur perpendicular equation is : y = 5x + 23 <==
Yes it’s a proportional answer
Y=3x+7
Formula- y=mx+b
B is y intercept
M is slope
Hope this helps!!
If there is no relation between x and y, it is said that their is "no correlation."
