A quadratic equation is usually in the form:
where a, b and c are the coefficients of the expression and a ≠ 0.
If a = 0, the equation becomes a linear expression and is no longer quadratic.
Hence, in the above options; y = 5x -2 is the only one that is not a quadratic equation.

Step-by-step explanation:
Conversion factors:
1 km = 1000 m
1 m = 100 cm
1 h = 60 min
1 min = 60 sec
48.6 km/h = 81,000 cm/min = 13.5 m/sec
