Question

what is the y intercept of the equation 2x+y=7?

Answer 1

well you use the equation:
y=?x+?
you need to rearrange it so y is at the front, so...
2x+y=7 (minus 2x)
y=7-2x (change it)
y=-2x+7
now you can see that 7 is last.
This means that the y intercept is 7
hope it helps :)

Answer 2

i think its 7

Answer 3

2x+y=7
y = -2x + 7
=> y intercept = 7
