Is y = 19x - 5 proportional or non-proportional

non-proportional because it has a y-intercept

The given equation of the line is non proportional.

Step-by-step explanation:

If y is proportional to x then it will be represented by y ∝ x

Or y = kx where k = proportionality constant

And this linear equation when graphed, the line passes through (0, 0) and there will be no y-intercept.

But the equation y = 19x - 5 given in the question shows the y intercept of (-5).

Therefore, this equation can not show the proportionality relation between x and y. It's non proportional.
