Hi there! :)
We are given the slope of the line: -4.
We are also given its y-intercept: 1.
We are asked to write the equation of the line in slope-intercept form.
Now, slope-intercept form looks like so:
y=mx+b
m is the slope, and b is the y-intercept.
Therefore, all we have to do is plug in the values:
y=-4x+1
Therefore, that's the answer. Hope it helps.

Good luck.
