Answer:

y= -0.25x-1.

Explanation:

1) if slope =-0.25, then in slope-interception form y=-0.25x+i, where i - unknown interception;

2) to calculate the unknown interception 'i', it needed to substitute the given coordinates (4;-5) into the equation:

-5=-0.25*4+i, ⇒ i=-1;

3) finally, y= -0.25x-1.
