We know that y=mx+b
where m is the slope of the line and b is the y intercept which cleary is 2 in this case.
Now, when y=0 then x=5
putting the values we get 0=5m+2, then m=-2/5 which is the slope of the line.
Now, putting m=-2/5 and b=2 in equation y=mx+b we get our equation as 5y= -2x+10 which is E
where m is the slope of the line and b is the y intercept which cleary is 2 in this case.
Now, when y=0 then x=5
putting the values we get 0=5m+2, then m=-2/5 which is the slope of the line.
Now, putting m=-2/5 and b=2 in equation y=mx+b we get our equation as 5y= -2x+10 which is E

Hey Shilpa, Thanks for the explanation but 5y= -2x+10 is option C not E. Is it a typo error?
