PLS HELP ME

4.) Write the equation of the line shown below? SHOW WORK!

y=1/5x-3/5

Explanation:

Use points (3,0) and (-1,-1) to find the slope and y-intercept.

Use y1-y2/x1-x2 to find slope

-1-0/-1-4
=-1/-5
=1/5

So the slope is 1/5

Then use y-y1=m(x-x1) to find the y-intercept.

y-0=1/5(x-3)

y-0=1/5x-3/5

So the equation is y=1/5x-3/5

< i think this is the answer unless i did my math wrong
