Y + 6 = 4/5( x + 3)
y + 6 = 4/5x + (3(4))/5

y + 6 = 4/5x + (12)/5
y + 6 = 4/5x + 12/5
y + 6 (-6) = 4/5x + 12/5 (-6)
y = 4/5x + 12/5 (- 30/5)


y = 4/5x - 3.6 ( y = mx + b formula)

4/5 = 0.8

y = 0.8x - 3.6

x = 1
y = 0.8(1) - 3.6
y = - 2.8

x = 2
y = 0.8(2) - 3.6
y = 1.6 - 3.6
y = -2

x = 3
y = 0.8(3) - 3.6
y = 2.4 - 3.6
y = - 1.2

x = 4
y = 0.8(4) - 3.6
y = 3.2 - 3.6
y =  - 0.4

x = 5
y = 0.8(5) - 3.6
y = 4 - 3.6
y = 0.4

etc.

graph  using the (x,y)

connect the dots

hope this helps

Molly owes her brother $300.She works for $10 per hour as a checker at the local grocery store.Molly plans to repay her brother
gavmur [86]

Answer: The expression which represents the condition described is given as  4x=300

Step-by-step explanation:

Since we have given that

Amount that Molly owes her brother = $300

Let the number of hours she worked as a checker be x

Cost of per hour = $10

Amount she get after doing work for x hours is given by

10x

Rate of tax are taken out = 80%

So, amount she left with is given by

\frac{100-20}{100}\times 10x\\\\=\frac{80}{100}\times 10x\\\\=8x

So, Molly plans to repay her brother half of what she earns is given by

\frac{8x}{2}=4x

According to question,

4x=300\\\\x=\frac{300}{4}\\\\x=75\ hours

So, the expression which represents the condition described is given as

4x=300
