y intercept at $y=4$
x intercept at $x=1$

This is an equation of a straight line $y=mx+c$

$color(blue)("Determine the x intercept")$

The graph crosses the x axis at y=0

$color(brown)(y+4x=4)color(blue)(->0+4x=4)$

Thus $color(green)(x_("intercept")=1)$

$color(blue)("Determine the y intercept")$

The graph crosses the y axis at x=0

$color(brown)(y+4x=4)color(blue)(->y+4(0)=4)$

Thus $color(green)(y_("intercept")=4)$

How do you find the x and y intercepts for y + 4x = 4 y + 4x = 4 ?
