Answer:
y=-5x+5
Explanation:
y=mx+b, where m is the slope, and b is the y-intercept
the slope can be solved by looking at the rise over run, which is -5 over 1, making a slope of -5. The y-intercept is found m=by viewing the point at which the line crosses the y-axis, which is at (0,5), so the y-intercept is 5.
