The scatter plot below shows the number of pizzas sold during weeks when different numbers of coupons were issued. the equation represents the linear model for this data. y = 3.4x + 43 according to the model, how many more pizzas are sold for each additional coupon issued? 1 pizzas 3.4 pizzas 4.3 pizzas 43 pizzas 46 pizza a graph measuring average number of pizzas sold nightly in relation to number of coupons issued. a line indicates that pizzas sold increases as number of coupons issued increases

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

the answer on e2020 is

10

4/5

3/5

4/3

step-by-step explanation:

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
