Answer

slope = -0.8 y-intercept = 0.4

Work Step by Step

You are given this formula $y=0.4-0.8x$ You can arrange the formula to match the standard slope-intercept form: $y=-0.8x+0.4$, which is in the form $y=mx+b$. Once the given formula is in slope-intercept form you can easily extract the slope and y-intercept.
