Jul 24, 2015

y-intercept $=0$
x-intercept $= 0$

Explanation:

Given $y = 4x$

The y-intercept is the value of $y$ when $x=0$
$color(white)("XXXX")$ $y = 4(0)$ $color(white)("XXXX")$ $rarr$ $color(white)("XXXX")$ $y=0$

The x-intercept is the value of $x$ when $y=0$
$color(white)("XXXX")$ $(0) = 4x$ $color(white)("XXXX")$ $rarr$ $color(white)("XXXX")$ $x=0$
