Question

What is the y-intercept of the function f(x)=4 – 5x?

Answer 1

When a function is in the form of slope-intercept, \(y=mx+b\), the y-intercept will be the \(b\) value.
Here your function has been arranged in \(y=b-mx\)... so you need to rearrange it.

Hint:\[f(x)=4-5x\longleftrightarrow y=b-mx\]

Answer 2

Oops... I mean, \(b+mx\). The slope \(m\) can be negative.
