Question

Which functions are linear?
y=4/x
y=-4x + 1
y= 5(x – 0.6)

Answer 1

y=-4x + 1

y= 5(x – 0.6)

Explanation:

y = -4x + 1 follows the linear equation of y = mx + b.

y = 5(x - 0.6) can be simplified into y = mx + b by distribution,

y = 5x - 3 which follows the linear equation of y = mx + b.
