Please help fast if you answer both answers correctly I’ll give you double the points plus brain list only if you know please type

4

Step-by-step explanation:

20: 1, 2, 4, 5, 10, 20

28: 1, 2, 4, 7, 14, 28

The GCF is 4 because that is the highest number that can divide both 20 and 28 evenly.

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. : )
