Answer:
The given equation of the line is non proportional.
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.
