All I need are four equations of parallel lines

questions

1) through: (2, 3), parallel to y = 4x - 1

2) through: (5, -4), parallel to y = -

3/5x +1

3)through: (1, 2), parallel to y = 6x + 3                                                        

4)through: (-1, -1), parallel to y = -4x + 1

answers=

1)y = 4x - 5

2)y = - 3/5-1

3) y = 6x - 4

4)y = -4x - 5

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

21.4 i did it already for s1
