Question

A student said that the y-intercept of the function y = 3 · 4x is 4. What is their mistake? What is the actual y-intercept?

Answer 1

Answer:

The y intercept is 0

Step-by-step explanation:

the equation of a line is given as

$y= mx+c$

where

m= is the slope

c= is the y intercept

their mistake is that they did not recall that if the "c" is not shown, it is assumed to be zero (0)
