Write slope intercept equation passing through (-5,0) and (0,4/5)

First find the slope by calculating rise (change in x) over run (change in y).

(4/5)-0/0-(-5)

(4/5)/5=0.16

The y intercept is 4/5. We know this because y interceot is the value of y when x is 0.

Then plug this into y=mx+b where m is slope andb is y intercept.

Final y=0.16x+0.8 or y= 4/25x+ 4/5
