Answer:
y = -1/4x - 1
Step-by-step explanation:
y=mx+b
the y intercept is -1, and the slope is up one, left four
y=-1/4x-1
The Y intercept is at -1 so the end of the equation should be -1 and not -4.
The graph is decreasing by 1 block down every 4 blocks to the right so the equation needs -1/4x as the slope.
Sorry I'm bad at explaining this.
