What is the y intercept y=4x + 5y = 80?

Answer 1

Best Answer - Chosen by Voters

You probably mistyped and meant that 4x + 5y = 80

Y intercept is when X = 0 (because that's when the line meets the y-axis)

so

4*0 + 5y = 80
y = 16

y intercept is at (0,16)

Answer 2

I think you meant 4x+5y=80
subtract 4x then you have 5y=80
Divide by 5 and you should be left with y= -4x/5+16
the 16 is when you divide 80 by 5
you y intercept is 16. Comes from y=mx+b
where b is the y intercept. Hope this helps
