Answer:
y=1/5x-4
Explanation:
use y=mx+b where m is the slope and b is the y-intercept
look at the graph and find the numbers to plug in
calculate the slope by finding two points the line goes through
then use rise over run so y/x so 1/5 is the slope
-4 is the y-intercept then plug those in to get the equation of the line
Hope this helps! :)
