The equation yˆ=105.416x+1249.309 models the amount of money, in dollars, a charity raises during an annual event when x people attend the charity dinner.

what does the y-intercept of the equation represent in context of the situation?

it costs the charity $105 to host the dinner.
if no one came to the dinner, the charity would still raise about $105.
it costs the charity $1250 to host the dinner.
if no one came to the dinner, the charity would still raise about $1250

  If no one came to the dinner, the charity would still raise about $1250

Step-by-step explanation:

The variable x represents the number of people who attend the charity dinner. When x=0, no people came to the dinner.

The variable y represents the amount of money raised (in dollars). When x=0, the value of y is about 1250. That is, the charity raises about $1250 when no people came to the dinner.
