Answer:
y = 25
Step-by-step explanation:
Given that the quantities are proportional then the equation relating them is
y = kx ← k is the constant of proportion
To find k use the condition y = 10 when x = 6
k = 
= 
= 
y = x ← equation of proportion
When x = 15, then
y = × 15 = 5 × 5 = 25
I don’t know if this is a proportion but it’s a fraction....

I hope this helps
Ya have a wonderful day ^v^
For a line to be perpendicular to the x-axis in a 2 dimensional space, it must be composed of points with the same x coordinate and varying in the y coordinate.
X is, therefore, a constant and since the line goes through (-3,1), the equation we are looking for is:
X = -3
