The equation of a parallel line will have the same x-term, but a different constant (y-intercept). The required value can be found by putting the given point values in to the equation to see what it needs to be.
... y = 5x + ___
... 8 = 5·4 + ___
... 8 - 20 = -12 = ___
Your equation is ...
... y = 5x -12
Answer:
400 guitars
Step-by-step explanation:
200+200=400
x=10 , y=20
2x=x+10
2x–x=10
x=10
y=2x
y=2(10)
y=20
y= -1/3x+1
B
4÷2=2
14÷2=7
making it a equal ratio
