Question

Which of the following functions has a constant slope?

O y = 3x - 5
O y = 5x^2 - 4x + 6
O y = 3x^3+ 9x%2 - 8x + 11
O All of the choices

Answer 1

y = 3x - 5.

Explanation:

A linear function ( highest exponent is 1) has a constant slope.

So it's y = 3x - 5 - with constant slope value 3.

Answer 2

y=3x-5

Explanation:

y=3x-5 is a linear function. Linear functions are those whose graphs are straight lines. Slopes of straight lines are constant
