This is a classic example when the parts of the equation has been confused.

Step-by-step explanation:

Here the slope, which is the change in y for every change in x, is 3, and the y-intercept, is 5. The form of a line is y=mx+b. Jacob confused these two and chose D incorrectly, which has the form y=bx+m.

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
