And form a right angle at their point of intersection, b.
if the coordinates of a and b are (14, -1) and (2, 1), respectively, the y-intercept of is and the equation of is y = x + .

if the y-coordinate of point c is 13, its x-coordinate is .

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
