Question 6068
The equation is written in the slope-intercept form {{{y=mx+b}}} where mx is the slope and b is the y-intercept. The slope of a line is a ratio. 
{{{y=-0.25x+0.4}}}
 According to the formula mentioned above -0.25x or -1/4x is the slope and 0.4 is the y-intercept. We express is as (0,0.4)
Hope it helps
