If f (x) is parallel to the line y=3/4x+2/5, which function could be f (x)

If f (x) is parallel to the line y=3/4x+b, it would have to have the same slope.

In this equation:

y=mx+b

m = is the slope of the line.

A line parallel to the line y=3/4x + 2/5 must have the same slope; that it is to say, the slope would be m=3/4

Examples:

y=3/4 x + 50000

y=3/4 x - 51/36

y=3/4 x - √2

These functions could be parallels to the line y=3/4 x + 2/5
