m slope
n y-intercept
for:
m = -5
x = -2
y = -6

find n and insert it into the first equation
For direct variation:
y = kx
-12 = 9k
k = -12/9 = -4/3
Therefore, the required equation is y = -4/3 x
The function of earnings f would be f(x)=50+4.25x. After six hours by pluggin in 6 to the equation you would get $75.5 overall.
Answer:
The answer is b- 1/4 = 4 3/4
Step-by-step explanation:
B stands for the total amount of chocolate bars they started with.
Gabby ate 1/4 of those chocolate bars.
4 3/4 of the chocolate bars were left after that.
So, total amount of bars - what Gabby ate = chocolate bars that are left
b - 1/4 = 4 3/4
