write the equation of the line in slope-intercept form. It has a coefficient of m=-1 and pass through the point (9,4)

y=-1x+13

Step-by-step explanation:

There is a negative slope we start at (9,4) and go up one and to the left one. Eventually we well pass the y-axis at 13.

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
