Adele and monte are discussing graphs with negative correlation. adele claims that only graph b has negative correlation. monte claims that both scatterplots have a negative correlation. adele is correct because only lines may have a negative slope. adele is correct because the y values increase as the x values decrease in graph a, so it shows a positive correlation. monte is correct because both graphs show a strong correlation. monte is correct because in both scatterplots, the y values decrease as the x values increase so both have a negative correlation.

Answer - D

Negative co relation means that x and y are inversely proportional.

x decreases then y increases

x increases then y decreases

So, only D option satisfies this condition.

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

5 x 14?
