A scatter plot of data compares the number of posters (x) sold and its price in dollars (y). It contains the ordered pairs (20,12) and (30,15). Write an equation in slope intercept form for
the line of fit for this situation. Use this prediction equation to estimate how many dollars 50
posters would cost.

Step-by-step explanation:

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
