answer: 2.5 :)
The linear function has the form y=mx+b, which I expect you have heard of. The 'b' is the y-intercept, and the 'm' is the slope. A constant of proportionality is something you have with direct variation, which is where the line goes through (0,0). This happens when 'b' equals zero. So now the equation is just y=mx, and the constant of proportionality is 'm'.
If the equation is y = kx then the constant of proportionality is k.
5x=11y
If two variables, X and Y, are in direct proportion then Y = c*X for some fixed value c. This value, c, is the constant of proportionality for this relationship.

Various options: y is directly proportional to k, with x as the constant of proportionality; y is directly proportional to x, with k as the constant of proportionality; x is inversely proportional to k, with y as the constant of proportionality; x is directly proportional to y, with 1/k as the constant of proportionality; k is directly proportional to y, with 1/x as the constant of proportionality; and k is inversely proportional to x, with y as the constant of proportionality.
The constant of proportionality for y = 0.95x is 0.95
The constant of proportionality for y = 0.95x is 0.95
The constant of proportionality for y = 0.95x is 0.95
It is a linear function passing through the origin. It represents a direct proportionality between x and y.

The constant of proportionality in the relationship y = 30x is 30. This means that y is always 30 times the value of x.
If the equation is y = kx then the constant of proportionality is k.
5x-y equals 18 = -13
If y equals 5x-15 and x equals 1 then the value of y comes out to be -10. So y equals 5x-15 is -10.
Yes.
