John says the Giants will win the Superbowl. We agree on that.
When two or more people "agree to" an action, they have come to an agreement about an action involving an issue, proposal, decision etc.
John proposed that all members pay $2 a week in dues. The members agreed to pay the dues.
People can also "agree to" a proposal, but they can also "agree with" a proposal.
