Which is the equation of a line parallel to the line with equation y = 3x - 4 A. x + 3y = 4
B. x - 3y = 1
C. 3x - y = -2
D. 3x + y = 7

C. 3x - y = -2

Step-by-step explanation:

We know that lines with the same slope are usually parallel

3x - y = -2

-y = -3x - 2

y = 3x + 2

They have the same slope so we can assume that they're parallel

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
