Best ResponseYou've already chosen the best response.1Before we look at graphs, can you come up with an equation for this function? Let's say the number of days is x, and the number of poems is y.

Best ResponseYou've already chosen the best response.1the number of poems = a function of the number of days y = a function of x

Best ResponseYou've already chosen the best response.0so the slope could be 2?

Best ResponseYou've already chosen the best response.1You can use the slopeintercept form: \(y = mx + b\) b is the yintercept. That is the number you have at zero xvalue. The slope is what accounts for what changes, in this case, daily.

Best ResponseYou've already chosen the best response.1the number of poems = a function of the number of days y = a function of x y = fixed beginning amount + daily additional amount

Best ResponseYou've already chosen the best response.1No. Look at my last line above. y, the number of poems, is the sum of the beginning amount and the daily additional amount. What is the beginning amount? Hint: "Billy started with 2 poems in his journal."

Best ResponseYou've already chosen the best response.0would the points be (4,2) and (0,2)

Best ResponseYou've already chosen the best response.1No. No x. The fixed amount never changes. It is not dependent on x. The fixed amount is simply 2 since Billy started with 2 poems in his journal.

Best ResponseYou've already chosen the best response.0Ok, so the points would be (0,2) (1,6) and (2,10)

Best ResponseYou've already chosen the best response.1The daily additional amount depends on the day. He adds 4 poems per day. Day is x, so after day 1 he has 4 * 1 extra poems. after day 2 he has 4 * 2 extra poems after day 3 he has 4 * 3 extra poems after day 4 he has 4 * 4 extra poems this pattern goes on and on... after day x he has 4 * x extra poems

Best ResponseYou've already chosen the best response.1Since y, the number of poems in his journal is given by the fixed number of poems he started with plus the daily additional poems, we can write: y = 2 + 4x which can be rewritten as y = 4x + 2

Best ResponseYou've already chosen the best response.0what would be some points if I graphed that?

Best ResponseYou've already chosen the best response.1Yes, your points are correct because they are all points in the equation y = 4x + 2
