The answer is word AND.

Step-by-step explanation:

A conjunction is a statement formed by combining two statements with the word - AND.

It is used to connect clauses or sentences and allows to form complex  sentences by avoiding the cluster of multiple short sentences.

For example:

I have two goldfish and a cat.

My mother brought a puppy and a kitten home with her.

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
