Zina sees a train with seven cars. Each car has 9 windows on the side that zina sees. Which number sentence can be used to find how man windows zina sees on the train in all

(7x9)/2

Step-by-step explanation:

7 cars times the number of windows for each car. Then divide that number by 2, because only one half faces Zina

Hope this helps

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
