For the piecewise function f (x) = { -3 + 7 -5 < x < -2 4 (x+2) -5 -2 < x < 5
x + 8 / 2 5 < x < 10 , which of the following represents its y - intercept when graphed?
(1) 7
(2) -5
(3) 3
(4) 4

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold

it's both, now can you answer my most recent question?
