Answer:
y = 
Step-by-step explanation:
Straight line in the graph attached shows the linear relation between number of gallons of white paint and number of gallons of red paint added to prepare pink.
Let the number of gallons of white paint required = x
and number of gallons of red paint required = y
y ∝ x
y = kx [k = proportionality constant]
Since a point (4, 1) lies on this line,
1 = 4k
k = 
Therefore, equation that describes the relationship will be,
y = 
Answer:
is the fourth one
Step-by-step explanation:
just replace x with the numbers given
and then work it out.
y=x-5
y=1-5=-4
y=2-5=-3
and so on
hope this helps
