Question

1. Is the line that passes through the points A(0,1) and B(2,5) parallel to the line that passes through the points C(0,7) and D(4,15)? To determine whether these two distinct lines are parallel, you simply need to calculate their slopes. What is the slope of AB←→?
I know for a fact that this one is 2.

What is the slope of CD←→? Say your response as a fraction, such as 3/14.

^This one, I am not entirely sure what the slope would be. If someone could help me out, I would be more than happy to reward the person with the correct answer with 5 stars and Brainliest! Tysm, need this asap!

Answer 1

You are correct that the slope of line AB is 2. To find the slope of the line CD, we can apply the slope formula again (like I assume you did with AB).

$m=\frac{15-7}{4-0}=\boxed{2}$

Therefore, since the slopes of lines AB and CD are equal, they are parallel
