Question

Which is parallel to the following y=2x+1

a. Y=2x +5
B. Y- =4 (x+1)
C, Y=(-⅓)x +4
D. Y= 3x +7

Answer 1

a. y = 2x + 5

Explanation:

f two lines are parallel to each other, they have the same slope.

The first line is y = 2x + 1. Its slope is 2.

A line parallel to this one will also have a slope of 2.

a. y = 2x + 5

• This line also has a slope of 2. It is a possible choice.

b. y = 4(x + 1)

• This line has a slope of 4. It will not be parallel.

c. y = (-1/3)x + 4

• This line has a slope of -1/3. It will not be parallel.

d. y = 3x + 7

• This line has a slope of 3. It will not be parallel.

Therefore, your answer is a. y = 2x + 5.

Hope this helps!
